Jennifer Aniston's sharing lots of stories with her old costars for the "Friends" reunion, but she did NOT reveal some life-changing news with them about having a kid ... as reports have claimed.

TMZ reached out to Aniston, and her rep tells us ... rumors of Jennifer being in the process of adopting a baby are "false and never happened."

Various European tabloids began circulating the story that Aniston made the adoption announcement to her "Friends" co-stars this past week while they were shooting the reunion.

That's not true, but as we reported ... Matthew Perry did confirm the gang was back together on their old TV set for the highly anticipated HBO Max special in a now-deleted Instagram post.

We also learned the reunion was shot over the span of 3 days at Warner Brothers Studios, and production utilized the original stage and the famous fountain from the OG series.

Here's something to make ya feel old ... Macaulay Culkin is now a proud parent!!!

Macaulay, best known as Kevin McAllister in the insanely popular 1990s 'Home Alone' movies, just announced the birth of his first child with his partner, actress Brenda Song.

Macaulay and Brenda welcomed their son, Dakota Song Culkin, into the world last Monday in Los Angeles. A rep for the couple says he was named after Culkin's sister who passed away in 2008.

The baby boy is healthy after weighing in at 6 pounds, 14 ounces.

It's pretty jarring to think of Macaulay as a father and not as little Kevin ... entire generations have grown up knowing MC only from his classic Christmas movies, and the Google holiday ads reprising his iconic role.

In fact, filming wrapped on the OG 'Home Alone' a few months before Macaulay's 10th birthday, and he was 11 years old when he played Kevin in the 1992 sequel.

Now, he's a first-time father at 40 ... and with baby Dakota joining the fold, Macaulay and Brenda will no longer be home alone. Also, their sleep will most likely suffer.

UFC star Nina Nunes just gave birth 6 months ago ... but tells TMZ Sports she CAN'T WAIT to get back in the Octagon and fight on Saturday!

Nina -- formally known as Nina Ansaroff -- had a baby back in September with her longtime partner Amanda Nunes, who happens to be one of the greatest combat sports athletes of all time!

Nina ain't too shabby herself -- she's the #5 ranked UFC strawweight -- and she's taking on fellow mom Mackenzie Dern on "UFC on ABC 2" on April 10.

Mackenzie made headlines herself back in 2019 when she fought Amanda Ribas just 4 months after giving birth ... and gave a pretty inspiring performance, despite losing the fight.

Nunes tells us she has tremendous respect for Dern ... and hopes the fight will show people you can be a mom and also kick ass as a pro fighter!

Nunes admits her delivery wasn't exactly smooth -- she had some serious medical issues that left her in rough shape.

But, as soon as she was cleared to work out, she got ripped in weeks -- just look at the photos! Amazing!

As for Dern, she tells TMZ Sports the respect with Nunes is mutual -- "The babies make us better athletes, better fighters, more motivated, more professional."

Both women tell us they're expecting a war -- but it's not personal ... and they expect to take pictures with their babies together after the fight!

Emma Stone is glowing big time ... 'cause TMZ's learned she's given birth to her first child!!!

Sources tell TMZ ... the Oscar-winning actress gave birth Saturday, March 13 in the L.A. area. No word yet on if they had a boy or a girl, but we're guessing Emma and hubby comedian/writer/director Dave McCary are thrilled either way.

We last saw Emma out about last month in L.A. ... looking elegant, but very ready for the baby to arrive.

Emma and Dave met when she was hosting 'SNL' in 2016, and he was directing a taped sketch for the episode. They kept their relationship under wraps for quite a while ... until they went public by attending the 2019 Screen Actors Guild Awards together.

Dave eventually popped the question in December 2019, which they announced on social media -- Emma looked pretty damn proud, showing off the huge rock, and Dave captioned his post with a simple double heart emoji.

Bindi Irwin gave her hubby one helluva gift on their wedding anniversary ... their first daughter!!!

'Crocodile Hunter' Steve Irwin's only daughter has announced she gave birth to Grace Warrior Irwin Powell on Thursday ... which also marked her 1-year wedding anniversary with Chandler Powell.

Grace weighed in at a healthy 7 pounds, 7 ounces and 20 inches. She was born at 5:52 PM. Bindi shared the news on Instagram and captioned it, "Celebrating the two loves of my life. Happy first wedding anniversary to my sweetheart husband and day of birth to our beautiful daughter."

Bindi also explained the meaning behind Grace's name. She said, "Grace is named after my great-grandmother, and relatives in Chandler’s family dating back to the 1700s. Her middle names, Warrior Irwin, are a tribute to my dad and his legacy as the most incredible Wildlife Warrior. Her last name is Powell and she already has such a kind soul just like her dad."

As we reported ... Bindi and Chandler got married last March and she said "I do" at the Australia Zoo in front of a limited crowd due to the pandemic. Bindi had said a lot of their planning, spanning nearly a year, had to be scrapped last minute because of COVID-19 ... including the size of the guest list.

Elizabeth Holmes won't be standing trial in July -- instead, she'll be giving birth, so prosecutors are hitting the pause button on criminal proceedings.

According to new legal docs, prosecutors and her defense team agreed to postpone Holmes' trial after the Theranos founder revealed she's pregnant and due in July. That's also when her trial was slated to begin.

Both sides now say they want jury selection to begin on August 31, but the judge still needs to sign off on that.

Elizabeth, of course, was the subject of the HBO doc 'The Inventor' -- who can forget that voice -- which chronicled her meteoric rise and fall with her company that was once valued at more than $9 billion.

Remember ... she's accused of making false claims about discovering a new way to revolutionize blood testing. She's been indicted for allegedly defrauding investors out of hundreds of MILLIONS of dollars and deceiving hundreds of patients and doctors with the bogus tests.

Elizabeth has pled not guilty. It looks like she'll get a month and change to settle into motherhood before she has to face the judge and jury.

Halsey just dropped a bombshell ... she's got a bun in the oven!!!

The "You Should Be Sad" singer definitely is not that now ... she made the surprise announcement Wednesday, posting three pics of her baby bump and adding the caption, "surprise!"

It's unclear when the photos were taken, but in the images, Halsey looks at least a few months along.

Halsey also dropped what appears to be a huge hint about the baby's father ... she tagged Alev Aydin in the post. The two have been hanging out a lot recently -- going back to October, at least -- and he's a writer and producer.

As we've reported ... Halsey just scooped up Liam Payne's Calabasas mansion for a cool $10,161,150. The 9,659-square-foot home has 5 bedrooms, plus a home theatre, giant library, beautiful backyard, pool, koi pond, waterfalls, gardens and a massage/meditation house. In other words, a pretty good nesting spot.

Halsey previously sparked pregnancy rumors back in 2019, rubbing her belly with then-boyfriend Evan Peters. She later clarified it wasn't a baby bump, just a stomach full of pancakes.

The wait is finally over, Gigi Hadid has revealed the name of her daughter with Zayn Malik ... Khai.

Gigi made the not-so-subtle announcement Thursday, updating her Instagram page bio to include "Khai's mom." Fans were quick to notice the change, and went crazy for the news.

A source close to the couple tells us Khai's name is a tribute to Gigi's grandmother -- on her dad, Mohamed's side -- who was named Khairiah. The name Khai also means "crowned" in Arabic whereas Zayn's last name "Malik" means "King" ... so baby Khai's name translates to "crowned king".

Gigi gave birth to Khai in September, and while she's shared a couple faceless photos of her new daughter, the public was left in the dark when it came to the baby's name.

It was just before Thanksgiving when Gigi shared a photo of herself holding Khai in a blanket with the caption, "A whole new kind of busy & tired ... but she’s da bestie so she got Christmas decorations early." Included was a photo of a decorated Christmas tree.

Emma Roberts is the proud new mother of a baby boy ... who seems set up to be quite the scholar one day.

Sources tell us the actress gave birth Sunday in L.A. to a healthy boy, whom she and the father, her BF Garrett Hedlund, have named ... wait for it ... Rhodes!!! We're told he weighed in right around 9 lbs and both Baby and Mama Bear are doing great after the delivery.

Emma hasn't been shy about showing off her baby bump either these past few months -- in fact, she just posed for a nice holiday shot a few weeks ago. She was also spotted out and about last Wednesday looking ready to pop.

This is Emma's first child, Garrett's too. The couple were first linked together shortly after Emma broke off her engagement with Evan Peters in the spring of 2019. While reports said they were keeping things caj at first ... the relationship clearly sped up, because it wasn't long before word of Emma's pregnancy surfaced, which she confirmed in August.

Nothing like a whirlwind romance to bring about a new life. Congrats to the whole family!!!

Where's Maury Povich when ya need him? Lil Pump's probably hearing him in his head, 'cause TMZ's learned the rapper is NOT the father of the baby he claimed was his. Let us explain.

Earlier this week, Pump posted a pic -- taken last Sunday on a yacht in Miami -- holding a baby boy. Cute and nothing out of the ordinary ... except the caption shocked his 17 million followers: "Baby momma ain’t s**t won’t let me see my son #fathers right."

That created a big stir on social media, and in the hip-hop world ... with several outlets reporting Lil Pump had disclosed he was a father for the first time, and was dealing with baby mama drama.

But, as MJ put it ... the kid is not his son!!! Sources tell TMZ the baby boy is actually the son of Andre Malek, a yacht captain who operates charters in Miami.

We're told the baby boy's known for taking pictures with celebs and hot women who hire his dad.

Hell, Andre's son even has his own Instagram account ... @CaptainAdorable305.

Earlier this year he took a pic with Cuba Gooding Jr. and the pic was captioned, "This not what I meant when I asked for some OJ...😅🙈."

Gigi Hadid's teasing fans, but still not handing out the gift they want for the holidays ... that first full-face shot of her baby with Zayn Malik. Patience, grasshoppers.

The supermodel decided to show her baby daughter off a little bit -- something she's rarely done since the little one was born in September -- along with several photos of Christmas decorations put up in her home.

Gigi still hasn't provided the world with a photo of her girl's face, but the shots of her daughter resting on her chest in a baby carrier are adorable nonetheless.

Zayn and Gigi are keeping mum, to the public at least, about her name, but it seems "da bestie" is an early nickname. Gigi wrote ... "A whole new kind of busy & tired ... but she’s da bestie so she got Christmas decorations early."

Based on the shots of Mom and daughter and the festive decorations, it appears Gigi's at their Pennsylvania home ... where she's been living for months during the coronavirus pandemic.

"No, I did not expect this at this point in my life but everything happens for a reason!"

That's Brittany Matthews -- Patrick Mahomes' fiancee -- getting pretty candid about her pregnancy ... revealing the two weren't planning on having kids before their wedding, but they consider it “the biggest blessing [they’ll] ever have!”

Matthews -- a fitness pro who's been dating the KC Chiefs QB since high school -- says she was on vacation when she found out she was preggers ... and almost didn't realize it at first!

"It's funny because I read the pregnancy test wrong at the beginning and I thought I was all good to go -- ready to party, vacation ya know let's do this! Then, I had a weird feeling and I went back and checked just to make sure and it said positive."

Brit admits she "freaked out" -- but notes Patrick was "just so sweet and supportive" and "things have just been great ever since."

No, they weren't "trying" to get pregnant -- but Brit says they weren't exactly "being careful either."

Britney and Patrick got engaged earlier this year -- and she was asked on IG Live if they'll try to speed up the wedding to tie then knot before the baby is born.

"Actually, had a meeting about this yesterday with our wedding planner," Brittney said.

"We have a few dates nailed down but we'll be having baby in 2021 and we plan to do a wedding and all wedding things in 2022."

In other words, SHE'S FREE TO BOOZE AT THE WEDDING Y'ALL!!

This may go down as the most rim-shakin' gender reveal of all time!!!

NBA guard Austin Rivers and his model girlfriend, Audreyana Michelle, got extra creative when revealing the gender of their baby ... by lobbing a ball to daddy -- and it poofed into a cloud of blue!!

The stunning Audreyana announced the baby on the way just days ago ... with a mirror selfie captioned, "social distancing failed."

Austin got in on the fun, too, saying, "Pretty much lol. Love you baby❤️"

Now, we know the newcomer is a baby boy ... with the couple posting the highlight of a reveal on Tuesday.

"It broke in the hand lol🤷‍♂️but yea it’s a boy. 😍 Blessed," Rivers said.

Austin and Audreyana went public earlier this year ... and have been as inseparable as you can be (considering dude was in the NBA bubble for a bit) ever since.

This is Austin's second child ... his baby boy, Kayden, was born in 2018.

Congrats to the couple!!

You've heard of the "Girl Dad" ... and now Katherine Webb is proud to be a "Boy Mom" ... with the NFL QB's wife announcing they're expecting their THIRD baby boy!!

Remember, Kobe Bryant famously boasted about having all daughters ... using the now-popular term to show pride in raising all girls in his household.

Webb is now going to be outnumbered 4-1 in her home ... with the married couple revealing their third boy is on the way in a gender reveal Monday.

"And God said...BAM! YOU’RE A BOY MOM 👦🏻👦🏻👶🏻," the former beauty queen said on Instagram. "PSA- prayers needed for my sanity 😄"

The Houston Texans backup and Miss Alabama USA 2012 welcomed their first son, Tripp, in May 2016 ... and Cash followed later in 2018.

BTW -- doesn't it feel like just yesterday the world was introduced to Webb via Brent Musburger at the 2013 national title game?!

As for A.J., he's clearly THRILLED by the news ... pumping his fists and yelling, "YEAHH, thank you!!!"

Don't be surprised if a couple of these boys end up following their dad and lining up under center someday.

Kourtney Kardashian is NOT carrying her fourth child with Scott Disick, despite some strong speculation she's pregnant.

As you know ... the trailer for "Keeping Up With the Kardashians" season 19 dropped last month, insinuating Kourtney and Scott are back together and she's having his baby.

Kourtney's recent Instagram post, featuring a shadow some eagle-eyed fans thought looked like a baby bump, kept the rumor mill churning ... but we've learned that's simply NOT the case.

Sources close to Kourtney tell TMZ ... she is not pregnant again and she's happy being a mother of 3. As for the 'KUWTK' scene, we're told it was taken out of context as a teaser.

Bottom line ... our sources say Kourtney and Scott are not together as a couple, they're just very good friends and co-parents.
