Breakups

"Grey's Anatomy" star Kevin McKidd is officially a single man, but it came at a high price.

Kevin's wife Jane had filed to end their 17-year marriage and the divorce is now final. They have joint legal custody of their 2 kids -- ages 17 and 15. As for physical custody, they agreed to a "nesting arrangement." The kids stay at the family home and the parents rotate in and out.

As for money ... Kevin will pay $22,440 in monthly child support, and will also pay for private school and summer camp. Jane will get $65,096 a month in spousal support, plus 20% of any income Kevin receives in excess of $3 million a year.

When the kids turn 18, Kevin's still not off the hook. Although his child support obligations will terminate, Jane will get an additional $12,147 a month in spousal support for 4 years.

They each get a house and will continue to share ownership in a third house in Malibu. She gets the 2014 Chevy Volt.

Nick Cassavetes' ex-wife has fired back at him after he accused her of stealing their child ... she says the famed director has engaged in shocking conduct that has forced her and her daughter underground.

Heather Wahlquist tells TMZ Nick is actually the one who stole the 13-year-old back in August, and claims it was done out of revenge.

Heather claims Nick sent a pic to their daughter showcasing his exposed ass. She also mentioned that he posted a meme of Kevin Spacey along with several games with the caption, "Who remembers having to blow these as a kid." The words are followed by emojis of women raising their hands.

She insinuates Nick is still upset she left him 5 years ago, saying he's now in a "revenge plot against my family and I'm terrified."

Heather says she spent Xmas Eve alone with 13-year-old Barbie, "scared that this will end bad." She claims Nick has parked outside her home, "taking pictures of us and following us all around town."

And there's this ... Heather acknowledges Barbie "loves her papa" and says she's heartbroken.

'Notebook' director Nick Cassavetes is on the hunt for his 13-year-old daughter, whom he says has disappeared ... and he says it's all a diabolical plot by his estranged wife.

Law enforcement tells TMZ ... Cassavetes filed a police report. He claims Heather Wahlquist has been on the run with Barbie for the last month. He says he has ferociously tried to gain contact with Barbie to no avail ... her phone has been shut off and Heather refuses to take his calls.

Cassavetes has filed a crime report claiming Heather is violating their custody arrangement and has effectively stolen Barbie from him.

Cassavetes tells TMZ, "My 13 year old daughter Barbarella Cassavetes has gone missing, her mother repeatedly ignoring and disobeying court orders and stipulations. Heather Wahlquist is on the run, refusing to let me see Barbie, ignoring mandatory court appearances, and evading law enforcement."

Georgina Chapman stands to get 8 figures if she divorces Harvey Weinstein today, but their prenup says he could fork out much more ... now that they've crossed the 10-year mark.

The Weinsteins' 10th anniversary was Friday, and while they obviously have nothing to celebrate ... the milestone triggers a major bump in spousal support. The prenup they signed in December 2007 says Georgina gets $400k annually for every year of marriage, if they divorce now.

Before the anniversary, that number was only $300k.

The docs also spell out her cut of their marital assets. For the first 5 years of marriage, Georgina gets $250k per year -- and for years 6 through 10, she gets $700k per year. That totals up to a lump sum payment of $4.75 million.

But wait, there's more -- a housing allowance. Mrs. W gets $25k per month of marriage, with a cap of $3 mil ... which they've reached after 120 months together.

Add in the 10 years of spousal support -- for another $4 mil -- and the grand total is $11.75 million.

The numbers are huge, but so are their bottom lines. Weinstein is reportedly worth north of $250 mil ... while Georgina's net worth is roughly $20 million.

This all assumes Georgina files for divorce sometime soon. We know she's hired a high-powered NY divorce attorney, but, so far, no docs have been filed.

The prenup does have a gag order of sorts -- they both agree not to publish diaries, memoirs, letters, stories, photographs, or do interviews referring to their personal biz or financial affairs. Ditto for movies and TV deals. Sorry, Lifetime.

Danica Patrick is officially single ... her 5-year relationship with NASCAR driver Ricky Stenhouse Jr. is over after the guy publicly pumped the brakes when it came to marriage.

How do we know? Because Danica shared her frustration about the relationship situation back in July.

Here's the deal ... 35-year-old Danica had pulled an April Fool's gag on social media claiming one of her rings was an engagement ring.

So, when we saw Danica and Ricky out we asked if there was any movement on the engagement front. She told us Ricky had not proposed but added, "I was ready yesterday."

That day never came ... and now the relationship is over.

Roughly 18 months after calling it quits ... Iggy Azalea and Nick Young came face-to-face at Craig's in L.A. on Sunday -- and it was definitely NOT sunshine and rainbows.

Swaggy (who plays for the Warriors) is in town to play the Lakers -- and stopped by his old stomping grounds for dinner. Just so happens, Iggy had arrived a few hours before and was still inside.

The two were only inside the restaurant together for a short while -- but afterward, Young broke it down for us ... and told us things are cordial.

In fact, he even gave us ADVICE on how to act when you run into your ex ... and it ain't half bad!

But, Iggy clearly didn't feel the same way -- because when a reporter claimed the two were on a "dinner date," Iggy unloaded on Twitter.

"Ryan Smith @ TheDailyMail i hope all your christmas gifts contain boxes of dried up chips of dog sh*t for trying to imply i would EVER, EVER have a dinner date with my ex who created a full human behind my back."

Remember, they broke up when it came out that Nick knocked up his ex-GF.

Iggy added, "The unfortunate thing about LA is there are not that many places people eat. You can be in the middle of one of the most important dinner meetings of your life; and randomly your ex and all his friends walk in the same place."

It's been a long, tumultuous journey filled with battles over custody, spousal support and even sex tapes ... but Mel B and Stephen Belafonte are officially divorced.

According to new legal docs ... a judge granted the dissolution of their marriage as of December 15. All that's left to work out now is the division of their property.

Jennifer Hudson is putting out a bunch of not-so-sly disses against her ex, David Otunga, which he says violates the gag order in their bitter custody war ... TMZ has learned.

David filed docs this week calling out Jennifer for allegedly throwing repeated public jabs his way. In the docs, David points a Dec. 4 episode of "The Voice" where Jennifer is talking to Davon Fleming, one of the contestants. She makes a crack about her relationships never lasting.

In the docs, David also accuses Jennifer of shading him with an Instagram video where she's whispering about hate and jealousy. She never says David's name, but he thinks it's all about him.

He wants the judge to find Jennifer in contempt for violating the gag order.

"Shahs of Sunset" star Golnesa 'GG' Gharachedaghi believes her estranged husband is out to get her -- literally and figuratively -- and is asking a judge to keep him away ... from her cats too.

GG filed docs alleging Shalom Yeroushalmi has been harassing her and her family for months with calls, emails and texts ... and has repeatedly gone to the press trying to sell stories about her. GG claims as recently as this month, Shalom contacted TMZ and E! News in an attempt to defame her.

According to the docs ... GG has also caught her ex lurking around her house about 5 times, including back in February when he prevented a food delivery guy from delivering her order by posing as security.

GG's asking for an order to keep Shalom 50 yards away from her, Romeo and Malaika (her 2 cats). She also wants Shalom prohibited from contacting press or any social media outlets to offer info on her or her family. A judge denied the request, but set a hearing for her to bring evidence showing a restraining order is necessary.

As we reported ... GG filed for divorce from Shalom after just 2 months of marriage, but he's putting up a legal fight over it.

Mariah Carey is still Nick Cannon's dream girl ... at least she is in his latest music video, which features a diva doggie version of his ex.

Nick just dropped his Ncredible Gang vid for "Dream Girl" featuring Jeremih and Ty Money. We're told the song's definitely about Mariah -- Nick even sings "ain't over my ex."

Gotta love the concept -- Nick got adorable pooches to stand-in for the humans. Mimi, Nick and even their twins, Monroe and Moroccan, have doggie doppelgangers. Nick's is easy to spot -- he's the one in a turban. And watch for the Migos cameos as chihuahuas ... with locks!!

We'll say it ... this is bitchin'.

Tobey Maguire and Jennifer Meyer split up over a year ago but you could never tell from this photo.

Tobey came out to support his estranged wife Thursday night at a launch party at the Sunset Tower hotel in WeHo for an event celebrating her jewelry collection. She's partnering with Jenna Dewan Tatum and profits from the line go directly to a charity -- Baby2Baby, which supplies diapers and other baby-related stuff to low income families.

Despite being separated, neither has filed for divorce.

Tobey and Jen frequently hang out but their 2 kids are always there ... not last night.

Unclear if there's a reconciliation, but there's definitely smoke.

The guy who won the first season of "Survivor," Richard Hatch, has split from his husband, and plans on getting divorced ... TMZ has learned.

Richard tells TMZ ... he and his hubby of 14 years, Emiliano Cabral, are no longer together -- and they're headed to divorce soon.

Richard -- who's 56 years old -- says Emiliano, 42, met someone else much younger ... in his 30s.

Hatch tells us he's devastated by the turn of events. That said, he vows to keep living his life and is looking again for love.

Richard and Emiliano tied the knot in Nova Scotia, Canada in 2005 -- but we're told they had a private ceremony amongst themselves in '03. Richard says they split 2 months ago.

Naya Rivera has filed for divorce ... this after she was arrested for allegedly hitting her husband, Ryan Dorsey.

Naya cites irreconcilable differences for ending her 3-year marriage to the actor.

In her legal docs, filed by "Disso Queen" Laura Wasser, she's asking for joint custody of 2-year-old Josey. She also wants the court to block either of them from getting spousal support.

Naya previously filed for divorce in November 2016 but later dismissed it.

Sources tell us the arrest over Thanksgiving weekend was the last straw for her. As TMZ reported, Naya was arrested Nov. 25 for domestic battery after allegedly hitting Ryan in the head over a dispute involving their son. Interestingly, she lists the date of separation as Nov. 24.

Our sources say it's not the first time the police got involved in their marriage. We're told Naya called the cops on Ryan 3 times during their marriage.

Jeremy Meeks' estranged wife put him and his attorney on blast for slut shaming her, and going MIA on his son ... financially and otherwise.

Melissa Meeks just filed legal docs asking for child support and says he stopped paying for his kid. She says he left her to pursue his modeling career while she's left caring for their son, and she wants money from him. She says she's going broke paying the bills.

She also throws shade on Jeremy's attorney, Vicki Greene, saying, "Shame on Ms. Greene for attempting to slut shame me."

Melissa says Jeremy and Vicki criticized her for talking about her private parts on a reality TV show. She blasts Jeremy as a hypocrite, saying, "Jeremy struts around on a catwalk in his underwear and that's ok for our son to see, but my attempts to help shape my public image are wrong?? I would not even have a public image if not for Jeremy's tabloid adventures."

She adds, "I am shocked that Jeremy and his attorney attempt to slut shame me as they do."

Casey Affleck is officially single because his divorce from Summer Phoenix is final ... TMZ has learned.

Summer filed for divorce in July, citing irreconcilable differences. The couple has 2 sons -- 13-year-old Indiana and 9-year-old Atticus. They are getting joint custody of both kids.

Summer said the date of separation was November, 2015.

He had previously asked the judge to deny Summer spousal support but as we reported they came to a financial agreement and settled the conflict.

The couple was married for 9 years.

Blake Anderson finalized his divorce about as quickly as the law will allow ... TMZ has learned.

The "Workaholics" star's now ex-wife Rachael Finley filed for the big D back in late May -- and 6 months later they've reached an agreement and the judge has even given 'em a stamp of approval ... according to court docs.

The couple got married in 2012, and have a 3-year-old daughter. They agreed to joint legal and physical custody of her.

Under California law there's a cooling off period -- meaning even the smoothest of divorces have to wait 6 months -- which Blake and Rachael did.
