Breakups

Jay Mohr and wife Nikki Cox are off again, because he's filed for divorce for the second time.

Mohr had filed to end his 10 year marriage in July but withdrew the petition 6 days later, telling TMZ, he and Nikki were "Very in love. Very happy and that's really all there is."

Things apparently took a turn for the worse, because he filed Tuesday citing irreconcilable differences. This time around Jay wants joint legal and physical custody of their 5-year-old son. He also says they have a prenup that spells out all the financials.

After filing the first time Jay asked for an emergency order for full custody, claiming their child was at risk because of Nikki's alleged drug and depression problem.

John Mayer celebrated Taylor Swift's birthday not by throwing a party, but by throwing MAJOR shade her way.

John tweeted a not-so-subtle diss at his ex Tuesday -- her 27th born day -- calling it "the lamest day of the year." He pulled the classic post-and-delete ... which only makes it more obvious it was a shot at Taylor.

Dear John clearly still has some bad blood with T Swift.

On a happier note -- happy birthday, Taylor? Belatedly.

Christina El Moussa's marital status is complicated, to say the least, which explains why the "Flip or Flop" star is going out of her way to keep her wedding ring a mystery.

Paps got Christina out shopping Tuesday in the OC -- the first time we've seen her since TMZ broke the story about her separation from Tarek. She was rockin' freshly bleached roots, running errands and looking pretty carefree. As her shirt says, "Pink champagne can't complain."

She kept her left hand under wraps though ... so, it's unclear if she's still wearing a wedding band.

As we reported, Christina and Tarek are separating after what they call a "misunderstanding." Witnesses called it Tarek taking off into the woods with a gun ... causing a suicide scare.

As we reported ... the show will go on, and the former couple will keep working together. For now.

The wife of Broncos star Emmanuel Sanders is pulling the plug on their brief marriage, despite the fact she's about to give birth to their 2nd child any day ... TMZ Sports has learned.

Gabriella Sanders -- who is due this month -- filed divorce docs in Texas at the end of October, a few days before the couple's 3 year wedding anniversary.

According to the court docs, GS says "the marriage has become insupportable because of discord or conflict of personalities," but doesn't say exactly what caused the split.

It doesn't seem pretty, cause the judge gave Gabriella a temporary restraining order to keep the wide receiver away from her and their Texas home until further notice.

The judge did give the NFLer "limited access" to their 2-year-old son and future daughter.

In the docs, Gabriella's also asking for child support and a "disproportionate share" of their assets, because she says the divorce is Emmanuel's fault.

We reached out to his camp, but they had no comment at this time.

1:50 PM PT -- Gabriella had their baby girl Tuesday afternoon, and Emmanuel was there in the delivery room. He posted a pic which makes it seem like they buried their differences, at least for today.

Tarek and Christina El Moussa will still have to grin and bear seeing each other's faces after their separation -- HGTV's decided to keep shooting "Flip or Flop" with both of them.

TMZ broke the story ... the El Moussas separated after a bizarre incident earlier this year where Tarek bolted from their house with a gun, and Christina feared he was going to kill himself.

Producers must think the tension will make for a better show. HGTV tells us they "will continue production as scheduled" when it comes time to shoot season 8 of the reality show.

Sources close to production tell us the plan is keep showing them working together but, admittedly, no one knows if it's going to work. Season 7 is currently airing.

It's unclear if any of the drama leading up to their split will be featured on the show.

"Flip or Flop" stars Tarek and Christina El Moussa portray the chipper, nearly perfect all-American couple on TV but we've learned they're now separated ...after a scary incident involving guns and a feared suicide attempt.

Their ordeal started, at least publicly, in May when deputies responded to "a call of a possibly suicidal male with a gun" at the couple's Orange County home. According to law enforcement, a massive presence showed up -- 11 deputies and a helicopter.

Witnesses told cops they saw Tarek grab a gun from his safe, run out the back door and flee down a hiking trail. Shortly after, Christina was seen running out of the house crying and shaking.

Within minutes, the helicopter spotted Tarek on a trail and deputies told him to drop his weapon. Tarek complied and told deputies he had no intention of hurting himself. He said he wanted to "blow off some steam," and only brought the gun for mountain lions and rattlesnakes.

Deputies went back to the house and ended up seizing 5 guns, including an AR-15.

Christina and Tarek tell us they decided to separate while they reevaluate their marriage. As far as the incident goes ... they'll only say it was an "unfortunate misunderstanding."

They add ... they're committed to co-parenting, and ... "will continue to work through this process civilly and cooperatively, and plan to continue our professional life together."

Apollo Nida refuses to accept his divorce from Phaedra Parks is a done deal, and his reason -- spelling counts.

Apollo points out his ex's legal name is Phaedra Parks Nida, but in her divorce docs it's spelled "Nita" -- ditto for the spelling of his name in those docs.

He's now filed a motion to vacate her divorce, but not only due to the typos. In the motion, obtained by TMZ, Apollo says the 'RHOA' star took advantage of the fact he's in prison. He says there was a final hearing in July, but he was never notified of it ... and therefore, the divorce should be thrown out.

TMZ broke the story ... Phaedra's unsealed docs appear to back her claim she's been single since July, but if a judge buys Apollo's side of the story ... they could be back to square one.

Let's not forget ... Apollo filed his own divorce docs.

Sia and Erik Lang are headed for splitsville -- they're breaking up after a short 2 year marriage.

The couple tells TMZ that "after much soul searching and consideration we have made the decision to separate as a couple. We are, however, dedicated to remaining friends."

The couple moved things pretty fast ... announcing their engagement back in June of 2014, and then tying the knot just 2 months later.

Sorry Little Monsters, Lady Gaga and ex-fiance Taylor Kinney are not back together -- despite a pic of him with her mom -- the exes are just doing the conscious uncoupling thing.

Gaga and Kinney called it quits in July after 5 years together, so fans freaked when he showed up on Gaga's Instagram this week. Sources tell us they still have a great relationship and talk from time to time.

Kinney happened to be in NYC and found out Gaga's Born This Way Foundation was doing the Shared Kindness event at 30 Rock. Gaga's in Europe but her mom, Cynthia, helps run the foundation and Taylor offered to help her out.

Gaga was moved enough to post the pic of them at the fundraiser.

Oscar De La Hoya has proclaimed himself single -- which apparently means his longtime marriage to pop singer Millie Corretjer is down for the count.

The ex-couple who founded Barry's Bootcamp got a pretty even split in their divorce with one major exception ... she's getting the keys to the house.

Rachel Mumford filed for divorce from John Mumford back in May 2014, but they just reached a final settlement. They'll share custody, joint and physical, of their 2 teenage kids ... divvy up their bank accounts, and they get an equal share of their interest in the hugely popular fitness biz.

Rachel gets the prize ... their pad in Malibu. The divorce was nasty from the start ... with her dropping allegations of violence and drug abuse.

"Bachelor in Paradise" star Lace Morris is back on the market but she's absolutely certain about one thing -- the matching tattoo she got with ex-fiance Grant Kemp ... ain't going away.

Lace tells us even though she and Grant both got their couple name, "Grace," inked on their wrists, she's planning to keep it because it's not just about her ex and the broken engagement.

Lace says it's a reminder of good times she had with Grant, and memories of shooting 'BiP.' She says she always intended to get a tatt souvenir for her time on the show ... just so happens it ended up being about Grant when they got together.

We're told Grant's not rushing to remove the ink, but he's open to erasing it later. Translation: When a new hot chick wants it gone, he'll lose it.

As for the engagement ring -- reportedly worth almost $100k and bought by production, NOT Grant -- Lace says she's keeping it, unless producers demand it back.

Well, that was quick ...

Just weeks after announcing her split, Abby Wambach and Sarah Huffman have already barreled through the divorce process ... and are officially dunzo.

Bethenny Frankel's ex-husband is bristling over threats by her current boyfriend to sue him for trashing her in emails, saying he's forced to interact with the BF because the guy's constantly around his daughter.

Jason Hoppy fired off a letter to the lawyer for Dennis Shields, who threatened to sue Hoppy claiming he was sending a flurry of disgusting, harassing emails to Bethenny and cc'ing him.

Hoppy, who Shields claimed sent emails calling Bethenny ugly, old and irrelevant, never specifically disputed the content of what he sent, but he did say, "As a concerned father, I often have to contact others when I cannot reach my daughter through her mother."

Hoppy goes on to say as long as Shields is in his daughter's life, "I have no choice but to have some type of relationship with him."

George Harrison's son knows all things must pass, including his marriage, which he just filed to end.

Dhani Harrison is splitting from his wife of 4 years, Solveig "Sola" Karadottir. He filed the divorce petition last week, citing irreconcilable differences ... and based on the docs it could be a cleaner split than the average celeb divorce.

Naya Rivera's surprise marriage to Ryan Dorsey has fallen apart ... according to new court docs.

Naya filed for divorce last week, and -- according to her lawyer -- she's asking for primary physical custody of their 1-year-old son, Josey, with visitation rights for Ryan. The couple was married for a little more than 2 years.

You'll recall ... Big Sean said he broke off his engagement to the former "Glee" star back in the spring of 2014 after accusing her of being too controlling. Just a few months later, Naya was married to her longtime actor pal, Ryan -- seemingly out of nowhere.

Somewhere out there ... Big Sean is smiling. Probably.
