Paris Hilton holds no grudges, because she says inviting Kim Kardashian to her wedding is a no-brainer.

We got Paris and fiance Chris Zylka Saturday night in WeHo at Craig's restaurant, and she didn't miss a beat when our photog asked about Kim.

They've had an interesting relationship ... going from close friends to mortal enemies and then a grey area for years. We're told when they sorted it all out they realized they were good for each other and now get along just fine.

As for wedding planning ... that chapter begins this week.

"Fixer Upper" stars Chip and Joanna Gaines may have reason for concern over their unborn child ... and it centers around their ultrasound.

Joanna posted video of the ultrasound Wednesday after the couple announced they'd soon be welcoming their fifth kid. "Fixer Upper" fans speculated something was wrong with the images, because of excess fluid around the fetus. They've been commenting that the condition appears to mimic hydrops fetalis, a sometimes fatal condition.

Radiologist Nicole Saphier -- who has extensive experience in interpreting ultrasounds -- tells us there does appear to be skin edema (excess fluid in the skin). But Dr. Saphier is quick to add, although the ultrasound gives cause for concern, it's not conclusive. She says she'd need to see the whole ultrasound to determine if excess fluid is present in additional cavities such as the heart, lungs or abdomen.

Designer Michael Costello ripped off a makeup artist's face mask and tried slithering away with his own version on the runway ... this according to a new lawsuit.

The "Project Runway" darling from season 8 has been sued by special effects makeup artist Lauren Mountain, who says Costello hijacked her "Under the Skin Human Mask and Snake" face mask concept and used it in a fashion show without her permission.

According to the suit, obtained by TMZ, Lauren says Michael's relative, Stephanie, reached out to her to license Lauren's human skin mask design for a 2015 show she and Mike had planned for NYC Fashion Week.

But instead of paying her for the work, Lauren claims the Costellos recreated her mask on their own and strutted a model across the catwalk. She says they did credit her as the inspiration, but Lauren still isn't satisfied.

She's asking a judge for damages of at least $150,000. Michael's team tells TMZ "LOL," adding the validity of the lawsuit is ridiculous, and that the masks were, in fact, inspired by the '80s TV show "V."

Kim Kardashian and Kanye West have poured boatloads of cash into their Hidden Hills home over the past few years, but it was all worth it ... because the house is now $20 million ABOVE water.

Sources tell us ... the couple sunk around $20 mil into renovations since they bought the property -- once owned by Lisa Marie Presley -- in 2014 for $20 mil. It's been in a constant state of design, re-design, construction and expansion -- not to mention all the landscaping -- until they finally moved in a few weeks ago.

Now get this ... we're told Kim and Kanye had the property appraised ... and the estimated value is $60 million. Do the math, and they're in the black $20 mil.

"Little Women: LA" star Briana Renee is divorcing her husband and dropping some heinous accusations against him, including abuse, death threats and bestiality ... TMZ has learned.

Briana filed to divorce Matt Grundhoffer, her husband of more than 2 1/2 years, citing irreconcilable differences. As we first reported, Briana and Matt separated in November. She wants child and spousal support, according to the docs.

She also filed for a restraining order last month and in the docs, obtained by TMZ, Briana says Grundhoffer verbally abused her at least twice in November -- calling her a "c**t" and a "worthless bitch" ... and threatened to take their 1-year-old son, Maverick.

Briana claims Matt is frequently drunk, and threatens violence when he is. For instance, in April 2017 he threatened to "kill everyone in the house" and in June, he implied he was going to kill himself ... according to docs.

Most disturbing are the messages between Grundhoffer and another woman, which Briana claims she found. In the docs, she says they were "sexually explicit and disturbing" ... and allegedly "involved bestiality and proposals of sex acts with minor children, including the proposal of sex acts with Matthew's minor child, age 12, from a previous relationship."

The judge granted the restraining order -- Matt has to stay 100 yards away from Briana and their son. Briana's also been awarded full custody for now. We reached out to Matt ... so far, no word back.

"Teen Mom 3" star Mackenzie McKee is asking for prayers for her mom after discovering her illness is much worse than they thought -- she's been diagnosed with stage 4 brain cancer ... TMZ has learned.

A family source tells us Mackenzie's mother, Angie Douthit, had exploratory surgery Wednesday that revealed 5 large lesions covering her brain -- they initially thought it was only 3 -- plus masses in her lungs and several blood clots throughout her body.

Mackenzie said Tuesday the family thought Angie was dealing with bronchitis. After getting the cancer diagnosis she asked for prayers and added, "I’m devastated, I’m angry, I'm shook, I can’t breathe. You are everything. Please pray."

We're told the next step will be radiation treatments, once doctors have the full picture of Angie's cancer.

The news is especially shocking based on how fit and healthy Mackenzie's mom was -- they'd just competed in a diabetes awareness run in November and Angie whooped her.

McKee also called her mom "the healthiest person I know" and said she works out daily, doesn't smoke or drink, and the disease doesn't run in the family.

Christian Siriano is firing back at a retailer that says he pulled the plug early on a licensing deal they had with him, calling a batch of their clothes low quality and unapproved.

The "Project Runway" winner's company filed its own lawsuit against M&A Imports -- which owns the Just Love brand -- saying they're actually the ones who breached their contract ... by selling crappy dresses with his name on it that they allegedly didn't run by him first.

In the docs, Siriano says he only agreed to let M&A use his 'Christian Siriano' brand if they got his approval on pre-production samples of garb they planned to sell -- but says they failed to do so last summer, yet still moved forward with an inferior product.

Christian says the dresses were basically crap -- made of cheap fabric with major stitching, hemming and packaging issues ... which he was embarrassed to endorse with his name.

Khloe Kardashian's facing a big challenge in keeping her revenge body -- pregnancy -- but she's still giving it her best shot.

We got the mom-to-be at LAX Wednesday and asked her some tough questions about staying fit during pregnancy ... but even Khloe doesn't have all the answers.

Even so, she tells us she's exercising when she feels up to it and seems to be in great spirits ... all good news for mama and baby. Still no official reveal on whether she's having a boy or a girl, though.

As we reported ... Khloe and Cavs star Tristan Thompson are expecting sometime around late March, and he agrees with us -- she looks bomb at 6 months.

Season 2 of 'Revenge Body' premieres Sunday.

Tristan Thompson was gloating New Year's Eve about his soon-to-be baby mama and how fantastic she looks just 3 months before giving birth to their child.

Tristan and Khloe Kardashian were in a limo in Cleveland when he turned a cellphone camera on them and commented on the progress of her pregnancy ... and he gives her high marks.

Tristan underscored Khloe's reveal ... that she's due sometime around March. Kim's surrogate is due sometime this month. It's unclear when Kylie is due, but she's definitely pregnant despite her silence.

He revealed early on ... they're having girl.

Joe Giudice has a pretty cush prison stay ahead of him while he's locked up in Pennsylvania -- the place is like a damn resort ... even though it's got its own "deal breakers."

Like we told you, Joe was transferred from a federal prison in Fort Dix, New Jersey last month to a low security correctional facility in Allenwood, PA. Now, TMZ has learned exactly what's in store for him there -- and we gotta say ... it sounds nice for the pen.

First off, Joe gets access to a wide variety of food and products. He can buy stuff like butter pecan ice cream, a mackerel fillet, Thai tuna steak, and cappuccinos.

He can also buy Neutrogena shampoo, an MP3 player, and Skullcandy earbuds -- like we said, luxury living. If that doesn't convince ya, consider he also gets brunch every weekend, and can participate in yoga, fitness classes, bocce ball and even flag football.

Kyle Richards had a fellow "Housewife" with whom she could commiserate ... as she processes the burglary that left her jewelry box empty.

Kyle and Bethenny Frankel were in Aspen Saturday, bundled up and shopping at Gorsuch ... a high-end ski apparel store.

TMZ broke the story ... Kyle and hubby Mauricio Umansky had their Encino home hit over XMAS and the thieves cleaned her out and stole more than $1 million worth of bling.

As for Bethenny ... she's been in a never-ending custody war with ex-husband Jason Hoppy.

Tamar Braxton says the triggers that led her estranged husband Vincent Herbert to a jail cell on Christmas day were alcohol and a case of jealousy.

Tamar tells TMZ, "Co-parenting while going through a divorce is not an easy task. While celebrating the Christmas holiday as a family, after a few drinks and some jealousy, things got a bit out of hand, which is common for most families during the holidays. In the midst of everything our family is going through things got heated and a bit exaggerated."

Tamar makes it clear ... "There was no physical interaction between Vince and I on Christmas. While I do not appreciate his lack of respect for our family and him allegedly impregnating another woman, I cannot paint him as a vicious abuser that Vince is not."

TMZ broke the story ... Herbert was arrested for spousal assault and taken to jail, where he bailed out after posting $20k.

Tamar says, "I'm deeply hurt and saddened that this will be how we remember Christmas 2017, but, my motto is and maintains to be 'Bluebird of Happiness' and nobody will stop my joy and blessings going into the New Year! God Bless!"

Tamar went ham a few hours ago on the woman claiming Herbert got her pregnant ... calling her a "whore."

Mel B's ex-husband, Stephen Belafonte, hasn't moved on to 'Love & Hip Hop' star Nikki Baby -- even though they grabbed Xmas dinner together ... TMZ has learned.

A source close to Nikki tell us she and Stephen's dinner at Mastro's on Christmas day was just a business meeting to discuss a shoe line he's developing with her.

While they left in the same SUV ... we're told they were simply following behind another group that had joined them inside. Stephen brought some of his associates, and Nikki brought hers ... in other words, they didn't dine alone.

Former 'Real Housewives of Beverly Hills' star Carlton Gebbia says she and her family were very good to their housekeeper for 6 years, but the lady stopped showing up for work after a dispute over missing jewelry ... and now she's suing and trumping up a phony battery claim out of spite.

Carlton tells TMZ she had no idea she was being sued by her former housekeeper/nanny until she saw our story ... and while she's hurt by it, she says she's not necessarily surprised. Here's why ...

Carlton claims she recently noticed some expensive jewelry her husband David bought her over the years was disappearing ... and the housekeeper had access. Gebbia says she reluctantly asked her if she'd taken the jewelry after several pieces went missing ... she denied it.

Carlton says she asked her housekeeper to take a lie detector test to prove it and she agreed ... but then didn't show up for work the next day or the following 2 weeks.

Gebbia tells us the housekeeper returned after the 2 weeks away and asked for her job back, but the family decided to let her go.

'Real Housewives of Beverly Hills' alum Carlton Gebbia mopped the floor with her housekeeper, and the maid's now taking her to court ... and she says Gebbia even tried to kill herself.

The housekeeper -- referred to in the lawsuit as Jane Doe -- claims she was hired by Gebbia back in 2011 and toiled for 6 years as a housekeeper/nanny/chauffeur/grocery shopper/assistant.

Jane Doe claims Gebbia was often under the influence of alcohol and repeated physically, verbally and emotionally abusing her, including slapping her. She says 4 months ago, without provocation, a drunken Gebbia attacked her at her Bev Hills home.

She says the trigger was when Jane Doe texted Carlton's husband, David, and said Carlton had broken the TV in the movie room with a baseball bat. Jane Doe says when she tried to calm Carlton down, she became enraged, yelled at her and pushed her so hard, she fell against the door.

She says she was badly injured and was given 2 weeks off. She says the following month, she was fired.

Even more interesting ... the maid says over the last 6 years, Gebbia attempted to harm herself ... she mentions one incident in which she allegedly threw herself off the second story of her home.

The Kardashians have come out swinging in Blac Chyna's lawsuit against them in which she claims the fam sabotaged her reality show with Rob, saying it was all her doing.

As we reported, Chyna is suing Rob, Kim and Kris claiming they orchestrated a plot to torpedo "Rob & Chyna" after the couple broke up, and that's why E! canceled the show.

The Kardashians have just filed legal docs, courtesy of their attorney Shawn Holley, asking the judge to toss Chyna's case, claiming the real reason the show was canceled is that Chyna went to court and got a domestic violence restraining order against Rob, making it impossible to shoot a show with interactions between the 2.

It's important to note ... Chyna got a settlement in which she now gets $20k a month in child support and in return dropped the domestic violence allegations.

The Kardashians are also calling BS on Chyna's defamation claim, saying their allegations were true, including that she left Dream at home while she went out to party.
