Breakups

Gwen Stefani was wearing everything but a smile when "The Voice" star was spotted Friday afternoon out in LA.

It's the first pics of Gwen since she filed for divorce from Gavin Rossdale ... so, then again, not much to smile about.

Gwen Stefani has filed for divorce from her husband Gavin Rossdale, TMZ has learned.

Gwen cites irreconcilable differences in her divorce petition, which seeks to end their 13-year-marriage.

Gwen, who's repped by attorney Scott Weston, is asking for joint custody of the couple's 3 kids -- 9-year-old Kingston, 6-year-old Zuma and 1-year-old Apollo.

Gavin, who's repped by disso-queen Laura Wasser, filed his response at the same time, and he's also asking for joint custody. It's clear the petition and response were orchestrated to be filed simultaneously.

Sources tell TMZ there is no prenup, so the 50/50 California community property laws kick in. 45-year-old Gwen is worth a reported $80 million, and 49-year-old Gavin's worth an estimated $35 million. Given the length of the marriage, that will probably all go into one pot before it's divided.

Gwen checked the box on the form to deny Gavin spousal support.

In a joint statement they said, "While the two of us have come to the mutual decision that we will no longer be partners in marriage, we remain partners in parenthood and are committed to jointly raising our three sons in a happy and healthy environment."

Melanie Griffith has gone from a mega homeowner to a renter, but don't feel sorry for her.

Melanie's living it up as a single chick in an awesome Hollywood Hills home after making a record amount of money off the digs she used to share with Antonio Banderas. They scored $16 mil when they sold it earlier this year ... a record for the pricey Hancock Park area of L.A.

Melanie’s new 4,725 sq. ft. Mediterranean villa has 4 bedrooms, 4 ½ baths, a movie theater, sports court, and a large pool with a cabana overlooking the city.

She’s ponying up $50k a month for rent and with a 2-year lease she'll be paying more than a mil.

Scott Disick got a harsh dose of reality Friday when he went solo to the wedding of a friend, and seemed to express regret over his breakup with Kourtney Kardashian.

Scott attended the wedding of J.J. Corsini in Santa Monica, and posted a pic of his seating card with the caption,

"When u realize the grass isn't always greener"

It's pretty stunning and an enormous departure from a guy who seemed to revel in his newly-found freedom.

It looks like he's made peace with Kourtney, at least to the extent they have some sort of temporary custody arrangement.

Elisabetta Canalis will not saddle her baby with the name of any of her exes ... perhaps a shot at her most famous ex ... George Clooney.

Canalis and her surgeon hubby Brian Perri were hilarious leaving Mr. Chow Thursday night, with Brian making it clear there are lots of names off the table because Elisabetta had lots of BFs.

They're having a girl, so George would be improbable.

Then again, anyone ever see "Georgy Girl."

Sean Penn and Charlize Theron were back together Wednesday after they were forced to reunite in South Africa for re-shoots on the set of their movie ... six weeks after they ended their engagement.

To make matters worse ... Penn's the director of "The Last Face" and Theron's the star ... so he's her boss. Not awkward in the slightest.

Theron and Penn broke things off back in June after getting engaged in December 2014.

Ben Affleck is angry over allegations he's dating his children's nanny, so angry he's threatening a lawsuit.

A rep for Affleck calls the US Weekly story -- which claims Affleck and the nanny, Christine Ouzounian, began dating AFTER Ben and Jennifer Garner split but before they announced their divorce -- "complete garbage and full of lies."

The rep adds Affleck is "considering legal options."

Affleck and Garner announced their split last month after ten years of marriage.

Nothing helps you get over a D-vorce like a G-string ... just ask Lamar Odom ... who hit up a famous Vegas strip club this weekend ... just days after he and Khloe finally decided to end their marriage.

Scott Disick and Kourtney Kardashian kept it civil Thursday, when they had a meal together with the kids.

Scott, Kourtney, Mason and Penelope all had lunch at the Beverly Hills Hotel. We don't know if baby Reign was there.

After lunch, they drove in separate cars to Scott's Hollywood Hills home where she handed off the kids so he could spend time with them.

As we reported, Kourtney was at a Century City building Monday, and although we don't know who she saw, it's the building where attorney Laura Wasser works. She repped Kim and Khloe in their divorces, and we know Kourtney wants to work out a custody arrangement.

Scott Disick has begun the family healing process ... spending Wednesday with his son.

Disick took five-year-old Mason to Barnes & Noble in Calabasas, where the kid loaded up on toys.

Scott and Mason then went for an early dinner at Rosti Cafe.

Although he's been out of the picture for the past month following his split with Kourtney, Disick kept in touch from a far ... mostly thanks to FaceTime.

Brittney Griner was a woman scorned when she pulled the plug on her marriage -- because she learned Glory Johnson was texting an ex-boyfriend on the down-low ... during their engagement.

According to new annulment docs -- obtained by TMZ Sports -- Griner says she found out Johnson had been texting the guy in early April ... months into their engagement. Griner's point is she would never have married Johnson if she knew the old flame was still flickering.

Melanie Griffith and Antonio Banderas have taken the last step to end their marriage, by signing documents making their divorce official.

Court records show both signed the necessary legal docs to become officially single after 18 years of marriage.

Melanie was asking for full custody of their daughter, Stella, and also wanted spousal support. The custody issue resolved itself when Stella turned 18 last September.

A judge still needs to sign the docs to make everything official and that should happen in a matter of days.

It's her 4th divorce and his 2nd.

Blake Shelton filed for divorce because he believed Miranda Lambert was unfaithful, not once but twice ... TMZ has learned.

Multiple sources familiar with the situation tell us ... Blake has suspected Miranda was living out a country cheating song for months. We're told Blake heard rumors Miranda had hooked up with a country singer and thought it was believable enough to make him suspicious of her.

Chris Young opened for Miranda a few years ago, and the 2 were spotted out publicly from time to time. But our sources say the male singer was NOT the catalyst for the divorce. It was another guy, who is not a country singer.

Our sources say the reason Blake filed 2 weeks ago was because he received certain information about Miranda and the other guy that elevated things in Blake's head from rumor to fact.

Although the couple released a statement saying the divorce is amicable, we're told Blake has been very upset in the last few weeks and told her she had to get her animals off his Oklahoma ranch by Monday.

Michael Sam has returned to Hollywood ... hitting the club scene WITHOUT his ex-fiance ... and TMZ Sports has the video.

Scott Disick wasn't in a full-blown orgy this week as Kourtney Kardashian thought ... it was just an artistic endeavor.

Sources close to Scott say the pictures of hot girls flocking to Scott's Hollywood Hills home are deceptive. They were actually there for a music video shoot. We're told Scott let producers use his home because of the amazing view. It was so legit Mally Mall was there.

As for the chick who came out in Scott's bathrobe, we're told he insists it was all for a scene in the video.

Kourtney Kardashian is clearly done with Scott Disick, because she has a severe case of post breakup hotness.

Kourtney was leaving the Montage hotel in Bev Hills Friday, wearing chicly-tattered duds.
