Tristan Thompson is allegedly about to become a dad x3, this time with a woman out of Houston who claims she got pregnant after a brief fling with the NBA star ... and now wants him to pay up in the form of child support.

Maralee Nichols claims she's due to give birth to a baby boy today, December 3, according to new docs obtained by The Daily Mail. Nichols says the baby was conceived in Houston back in March ... around the time Thompson was in town to celebrate his 30th birthday.

The DM reports Thompson admits to having sex with Nichols several times at the hotel ... and previous to meeting up she had promised him a "birthday surprise" which he knew meant birthday sex.

If Nichols' timeline is accurate, Tristan was still publicly with Khloe Kardashian at the time he and the expecting mom hooked up.

One thing up for debate -- how long the fling lasted. Tristan reportedly says it was only a one-night stand, but Nichols says the two had been together off and on for around 5 months prior to the March hook-up.

As for Tristan and Khloe, they broke up in May, shortly after a woman named Sydney Chase made allegations she and Tristan had hooked up. Both Tristan and Khloe have publicly supported each other since the split and are often seen co-parenting their daughter True.

The baby boy would be Tristan's third known child.

Nichols is asking for child support and for Tristan to cover her pregnancy-related medical expenses.

Cody Bellinger and his model GF, Chase Carter, are officially parents -- the Dodgers announced the couple's baby girl has just been born!

Bellinger's team said in a social media post Tuesday that the newest Belli entered the world this week ... and revealed her name is Caiden Carter Bellinger.

The team congratulated the star outfielder and his significant other ... giving a "welcome to the world" caption to the latest member of the Bellinger family.

No official word yet from either Mom or Dad on the birth -- we're sure a post is being prepped as we type -- but the two both shared the Dodgers' post and are no doubt thrilled about the addition nonetheless.

As we previously reported, Chase -- who's been dating Cody for about a year now -- revealed her pregnancy on Instagram back in July ... and Cody was thrilled about it all at the time, writing on Chase's post, "Ay ay ayyyyyyyy!!"

The best part for Cody -- baseball season is months away from kicking off ... meaning Belli's got plenty of time to enjoy his new role as Dad.

Aaron Carter is a first-time father, welcoming his son, Prince Lyric Carter, to the world with fiancée Melanie Martin.

Aaron announced the exciting news Monday, posting a photo of his newborn and caption, "Emergency C Section after 13 hours of labor but my fiancé is in great health thank you lord and the incredibly sweet loving staff here. Prince is precious I love you son."

Clearly, it was an emotional event, as Aaron writes, "Your mommy loves you as I drop tears on the phone."

Aaron says he was the one to cut his son's umbilical cord, and writes to Melanie, "I’m so proud of you hunny you did it I Love you with all my heart my beautiful blessings from god."

TMZ broke the story, Aaron and Melanie had planned on naming their son Prince as a nod to Michael Jackson. Aaron and Michael were close, and of course, Michael was known as The Prince of Pop.

Evander Kane's divorce case has just taken another nasty turn ... the NHL player is now claiming his ex faked a pregnancy the last few months, and he's asking a judge to order her to take a mental exam to prove she's fit to care for their daughter.

It's all in new court docs, obtained by TMZ Sports, in which Kane says his estranged wife, Anna Kane, has been lying to him about her pregnancy since July.

The San Jose Sharks star claims up until earlier this month, he had believed Anna was pregnant with their second child, which was due in February 2022.

Evander says Anna had spoken about the baby often, and he says he had seen her belly grow with his own eyes throughout the last several weeks.

Evander, though, says after he reviewed recent medical bills -- it was brought to his attention that Anna had actually had an abortion way back in July.

Evander is accusing Anna of pretending to be pregnant for months ... going as far as wearing "some sort of pregnancy belly" to deceive him and cause him mental trauma.

Evander says all of it is so deeply disturbing, he's worried about the potential impact it might have on the couple's daughter -- and he's now requesting the court step in and give him full custody of their girl while also ordering Anna to undergo an examination to prove she's mentally stable.

For her part, Anna said in her own court docs that she did have the abortion in July, and acknowledged "I was less than forthcoming with [Evander] with regards to my decision."

She admitted in the docs that she "did not inform [Evander] or the court that I was no longer pregnant." She did deny, however, wearing any sort of prosthetics in an attempt to look pregnant.

Anna also claimed in her docs she is mentally stable and is fully capable of caring for the couple's daughter -- and is asking the court to deny Evander's requests.

Evander has been granted temporary custody of the child -- with a hearing on the matter slated for December.

Odell Beckham Jr.'s trade to Los Angeles is now officially the second biggest life event of the wide receiver's year so far ... 'cause the NFL star just revealed he's going to be a dad!

The new Rams player and his model GF, Lauren Wood, made the announcement Sunday ... with Wood going public with her pregnant belly for the first time in a social media post.

The model -- who's been dating OBJ for two years -- seemed to reveal the couple is having a daughter ... 'cause she captioned the pic with a girl emoji as well as three "I love you" comments.

Odell and Wood went IG official way back in November 2019 ... and they've been nearly inseparable since, with Wood showing up to his games often and also helping him through his various rehabs over the years.

As for soon-to-be grandpa Odell Beckham Sr. ... he was fired up to share the news Sunday too -- writing on his Instagram, "WHHHAAAA… #LOVEIT."

No word yet on when Baby Beckham is due ... but it appears there could be a chance it's at some point this football season.

Elon Musk's son upstaged his dad's rocket re-entry during a zoom presentation, and the kid made something clear ... he was not happy to get yanked from the action!

X AE A-Xii -- government name -- was on the lap of his 50-year-old pops during a conference about Elon's reusable rockets -- a feat even NASA has not been able to duplicate.

The boy was happily babbling in a zoom box as the folks at the conference had a choice ... focus on the rocket or the tyke. We're guessing the kid gave the rocket a run for its money.

Once the booster hit solid ground, someone opened the door and Elon's son made a very unhappy exit. You could hear him cry even after the door closed. Elon was slightly amused and then went on with the show.

Musk went on to tell those present at the National Academy of Sciences, Engineering and Medicine about his Starship spacecraft.

It's rare we see Elon interact this way ... he said after X was born, "Babies are just eating and pooping machines, you know. Right now there's not much I can do," adding Grimes, the baby's mom, is essentially the primary caregiver.

Elon and Grimes are no longer together, but they clearly share a love for X ... gotta say, the kid's adorable.

Ex-Atlanta Hawks forward Chandler Parsons says he's still trying to rebound from the serious injuries he suffered after getting hit by an alleged drunk driver in 2020 -- telling TMZ Sports his recovery process has been "intense."

The 33-year-old NBA player was in his 2017 Rolls-Royce when he was struck by another vehicle on Jan. 15, 2020.

Parsons was seriously hurt in the wreck -- his attorneys say he had a brain injury, disc herniation and a torn labrum -- and the hooper hasn't been on an NBA roster since.

So, when we got Parsons out in L.A. earlier this week -- almost two years since the accident -- we had to ask if he's trying to make an NBA comeback.

"We'll see," Parsons said. "Working out, staying in shape, but trying to still recover from the car crash last year, so we'll see."

Parsons says the recovery process has been hard ... adding, "Still kind of managing everything but still trying to work out."

While the rehab has clearly been a grind ... he's still gotten some great news through it all -- 'cause he and his fiancee, Haylee Harrison, just had a baby!

And, Parsons also shared an update on the couple's upcoming nuptials -- telling us his wedding is set to go down next October in Mexico.

Britney Spears sounds like she has more big plans now that she's a free woman once again ... openly thinking about having another child.

Yep, Brit's doubled down on her baby dreams Tuesday ... posting a picture of a small child standing on their tiptoes and saying ... "I'm thinking about having another baby!!!"

It sounds like Britney might want to have a girl ... at least that's the way her IG caption makes it seem. She wonders if the child in the pic she posted is a girl.

As you know ... Britney has 2 children with her ex-husband Kevin Federline, and they're both teenage boys.

Back in June, during her impassioned testimony, Brit said she wanted to be free to get married to fiance Sam Asghari, and have a baby. She complained the conservatorship was blocking her from doing so, but legally, that just wasn't the case.

In any event, she's definitely got baby on the brain now that the conservatorship is over after 13 years ... and she and Sam are planning their wedding.

She's got at least one family member on board with the idea of more kids ... her sister, Jamie Lynn Spears, "liked" Britney's IG post.

Of course, Brit hasn't liked much coming out of her little sister's mouth lately.

Exciting news for Mitchell Trubisky ... the wife of the Bills' backup QB just announced the couple is having a baby!!!

The signal-callers partner, Hillary Trubisky, revealed the two are about to be parents in a sweet post on her Instagram on Tuesday.

"Words cannot describe how excited we are to welcome Baby Tru into the world in May 2022," Hillary said.

In the photos Hillary shared, you can see how pumped the couple is ... showing off a sonogram while embracing each other happily.

Mitch got married to Hillary -- his longtime girlfriend -- in July at the Ritz-Carlton in Cleveland ... before they jetted off to Mexico for their honeymoon.

Now, in less than a year, Bills Mafia is going to get another member!

Shia LaBeouf may soon be living the dad life -- assuming he and Mia Goth are expecting ... and it sure looks like they are from this.

The actor was spotted at a Chuck E. Cheese restaurant Saturday with none other than his on-again, off-again girlfriend, Mia -- who might actually still be his wife, but more on that later -- where she looked very pregnant as they hit the arcade games together.

We're told it was just them there ... no other kids around. But, based on Mia's more-than-prominent bump, we'd guess she's got a bun in the oven -- and at least 4-5 months along. Disclaimer: We ain't doctors.

It's a little strange that 2 grown adults -- and potential parents-to-be -- would be gaming it up at a place for children, but maybe they're just getting ready for what's to come and preparing early. In any case, some congratulations could be in order here.

Shia and Mia have recently reconciled ... being spotted out together and getting cozy since at least last year -- this after his brief stint with FKA Twigs. They've even been seen rocking their wedding bands anew ... something most everyone thought was done with after 2018.

You'll recall ... SLB and MG got hitched way back in 2016, during a Vegas ceremony, but appeared to file for divorce a couple years later ... as each party was seen dating other people thereafter. It's unclear if they ever finalized, though, and quite possibly didn't.

If that is, indeed, the case ... then they could be married right now -- and not just that, may well be on first-time mom and dad duty in the near future. Neither of 'em have kids ... this would be their first -- again, operating under the presumption they are still romantically involved at this point ... which, by most accounts, they certainly appear to be.

Saweetie says she wants children in her life -- and one Nick Cannon seems to be ready to deliver ... if she wants to take him up on it.

The rapper tweeted out her parental desires Saturday, writing ... "I want some babies." Short and sweet -- no real other context either, but on its face ... it sounds like she's ready to be a mom.

While there were a number of normies in her comments who offered up their services to get that done -- Nick actually stood out among the rest with a not-so-subtle offer of his own ... retweeting Saweetie's message and adding a few telling emojis.

There's a curious face emoji, a ninja emoji, a laughing emoji, and a guy raising his hand emoji. The hand-raising says it all ... NC seems to be down to provide, and as we know -- is very well-equipped to do so.

The man has fathered several children over the course of his life, including three just earlier this year -- his son, Zen, and twins Zion and Zillion ... the latter 2 having a different mother. He's got four more from previous relationships -- including a couple with Mariah Carey, a couple more with Brittany Bell.

He's talked about going celibate for a while, but seems to have backtracked on that ... indicated here in his volunteering -- not to mention what he told us the last time we got him out. Remember, Nick said he'll keep having kids ... just so long as the man upstairs keeps on allowing it.

No word from Saweetie yet if his proposition sounds appealing or not -- frankly, she probably has a lot of would-be suitors who'd be willing to give it a go ... and could have just about whoever she wanted for this mission.

Aaron Carter is about to be a first-time father -- a baby that’s due any day now, and the kid's name will honor Aaron's relationship with Michael Jackson.

The singer tells TMZ ... his fiancée, Melanie Martin, has been expecting a baby boy for quite some time now. Her due date is Nov. 18, but he says they're ready for her to pop anytime between now and then.

Aaron says they've already decided the kid's name will be Prince Lyric Carter, which is a nod to MJ.

As you probably know, Aaron and Michael were close ... and he tells us the King of Pop -- who he considered a friend and mentor -- used to call him the Prince of Pop. Sooo, there ya go.

Anyhow, the young Prince-to-be might be arriving via c-section because of some high-risk factors for Melanie. We're told she has anemia and ulcerative colitis, plus the baby was in breech position -- feet first -- for the first 6 months of the pregnancy ... but he's back in a normal position now.

The couple says they're nervous, but mostly thrilled for Prince's arrival ... especially after Melanie suffered a miscarriage last year.

Britney Spears wants to get married, buy a house and have kids ... but those plans are all on hold until the judge in her conservatorship case decides if it should end ... TMZ has learned.

Britney and Sam Asghari are engaged, but sources with direct knowledge tell us they have not made any wedding plans because of the impending court hearing. Ditto the prenup ... there's been no movement. And, TMZ broke the story ... they want to buy a house together, but that's on ice as well.

All signs point to the 13-year-long conservatorship coming to an end, but it's not guaranteed. The wild card -- whether the judge orders a mental evaluation. Britney, Jamie and others have urged the judge to end it without such an evaluation ... in fact, so far no one involved in the conservatorship has suggested otherwise.

Nevertheless, with 13 years of mental evaluations on file with the court, it's up to the judge whether to cut Britney free without another one. The judge has an easy out given the parties don't want it, but given the various diagnoses over the years, the judge may want to hear from psychiatrists and other doctors before making the decision.

As for all her plans, Britney is living her life ... hanging with Sam, going on vacation and posting stories about her life on social media.

Cristiano Ronaldo's family is growing -- by TWO -- 'cause the international soccer superstar and Georgina Rodriguez just announced they're having TWINS!!!

The couple shared images of the sonogram from bed on Wednesday ... saying, "Delighted to announce we are expecting twins👶🏻👶🏻. Our hearts are full of love - we can’t wait to meet you ❤️🏠 #blessed."

This will be babies #5 and #6 for the Manchester United striker ... who's had 3 children via surrogate mother.

Cristiano Jr. is 11 years old, Eva Maria and Mateo are 4 and Alana, who Ronaldo and Georgina had together in 2017, is 3 years old.

Cristiano and Georgina have been together since 2016 ... and have sparked engagement rumors for years, but as of now, their official status remains a mystery.

Ronaldo has previously said he wants even more kids ... saying, "I want seven children and as many Ballons d'Or," he said. "As long as I play, I'll have the ambition to win all I can."

Jamie Lynn Spears says she went through hell when pregnant at 16, and her parents and team were a driving force behind her misery ... pushing adoption, abortion and going to great lengths to hide her from the public.

We've obtained several snippets from Spears' upcoming book "Things I Should Have Said" where she lays out the events that followed her telling her parents and management she was pregnant in 2007.

In one passage, Spears says people from her inner circle, "... came to my room trying to convince me that having a baby at this point in my life was a terrible idea … 'It will kill your career. You are just too young. You don’t know what you’re doing. There are pills you can take. We can help you take care of this problem … I know a doctor,'" adding, "everyone around me just wanted to make this 'issue' disappear."

Jamie Lynn says flatly, "...everyone was certain that termination would be the best course of action."

Spears says her phone was taken away to stop her from communicating with people outside her immediate circle ... the goal being to keep everything on the down-low.

Jamie Lynn claims she wasn't even allowed to tell Britney she was pregnant, saying, "I needed her more than ever and she wasn’t able to help me in my most vulnerable time … To this day, the hurt of not being able to tell my sister myself still lingers.”

At one point, Jamie Lynn says she and her dad Jamie got into a fight over the unborn baby, "slinging words and tossing insults" when he pushed adoption.

Spears says eventually her team made an exclusive agreement with OK! Magazine to break the pregnancy story, and give them the first images of Jamie Lynn's baby.

Jamie Lynn says she and her mom went to some cabin in where she thought was Connecticut to hide until the article came out. The two spent Thanksgiving there together, where "Momma wore her disappointment like her favorite jacket."

Jamie Lynn has come under a lot of heat lately from Britney fans who feel she's taking advantage of Britney's current situation to make a buck off the book, but if the snippets we've obtained are any indication ... she's also got a lot to say about how she was raised and her parent's tactics.

The book comes out January 18, 2022.

We talked about it on the latest episode of the TMZ podcast.
