Breakups

Chris Brown has never been good at breaking up with women ... something he proved again Friday night in L.A. during a concert -- when he formally announced he's single by putting Karrueche on blast.

It all went down at Power 106's annual Cali Christmas ... when halfway through Brown's set the singer asked the crowd if there were any single women in the house.

After a brief pause, you hear Chris say, "I'm single too!" ... he then throws a heaping pile of shade at his now ex-girlfriend, Karrueche Tran, saying, "F*** that b****!"

But he wasn't done ... after the show the singer posted a picture on Instagram -- with THREE Kardashian's on his lap, which frankly sounds impossible.

Ryan Seacrest has broken up with his girlfriend -- so we've learned -- and is out on the town with a new, attractive blonde chick.

Ryan was leaving the GQ Men of the Year party Thursday night at the Chateau Marmont in West Hollywood and his GF of more than a year-and-a-half, Shayna Terese Taylor, was nowhere in sight. That's because we're told Seacrest said bye bye.

Ed Sheeran always looks a little uncomfortable, but he kicked it up a notch when he ran into his ex-gf Ellie Goulding. Y'know ... the ex he says cheated on him with one of those 1Ders.

Typical, right? Boy meets girl, girl cheats on boy with other boy, boy gets super awkward hug from girl ... while strangers watch.

Nothing says you're 100% done with an ex like a laser burning his name away -- just ask Iggy Azalea ... who's finally getting her A$AP Rocky tattoo removed.

The "Fancy" singer went to the Beverly Hills office of tattoo removal king, Dr. Tattoff on Tuesday -- and walked out with a bandage on her left pinky ... where A$AP's name once lived.

Iggy got the tatt years ago when they were dating. When they split, she just had his name crossed out ... but now she's making a permanent change.

Finally ... room for some fresh Nick Young ink.

And just to drive home the point with Ellie ... Ed brought his new chick, Athina Andrelos to the event. One word -- upgrade.

Ellie, like Ed said ... "Don't f**k with my love."

It's a question for the ages ... if you're going to run into two of your exes at a party, would you rather have two separate awkward encounters ... or an enormous one?

One Direction's Harry Styles chose the second option at Monday night's British Fashion Awards in London ... where he schmoozed Kendall Jenner and Cara Delevingne.

Styles was linked to Delevingne last September and Jenner just a few months later.

The scariest part for Harry ... Kendall and Cara came to the party together.

Comparing notes ... worst nightmare.

Mama June is trying to repair her relationship with Sugar Bear, and he's game to give it a second try ... so she says.

June tells TMZ ... Sugar Bear is back living full-time in the homestead and they are "working on the relationship." She admits it was damaged and Sugar Bear is hurt over her decision to reignite her relationship with convicted child molester Mark McDaniel.

June says they don't consider themselves "back together" and it will "take a lot of work" to regain his trust.

She tells us she did see McDaniel after he was released from prison in March ... something she lied about after we broke the story. But now she says, "I'm human, I made mistakes and done wrong, but no one is perfect."

June says she no longer has any contact with McDaniel.

Robin Thicke is clearly thankful for one thing this holiday season ... his super hot new girlfriend.

Thicke was rolling through Malibu Friday with the top down ... showing off 19-year-old April Love Geary -- and the guy looked pretty damn care free.

Robin's had a tough year -- see here, here and here -- so he's gotta be stoked to be moving on.

Plus, April looks really hot naked. That always helps.

Floyd Mayweather is firing back at his ex-fiancee Shantel Jackson -- claiming he did NOT violate her right to privacy by discussing her abortion in detail on social media ... because their relationship was for public consumption anyway.

As we previously reported, Jackson sued Mayweather earlier this year for a bunch of different reasons -- including assault, battery, defamation, invasion of privacy and more.

Now, Floyd is trying to get the several claims dismissed -- and in new legal docs, he focused on her claim that he violated her right to privacy. He starts off his argument in the most Mayweather way possible:

"At age 37 I am an undefeated boxer. I have been the world champion in five different weight divisions."

He goes on to explain that when he met Jackson, "she asked me to help her become famous" ... and stated that her only semblance of fame was appearing in 7 music videos.

Floyd says he used his celebrity to help build her up -- and says they became so famous, people were interested in every aspect of their relationship ... including the breakup.

Which is why Floyd says he went to social media earlier this year and told the world he ended things with Shantel because she had an abortion behind his back.

"Both parties are public figures. Abortion is a public issue," Mayweather states in the docs.

He adds, "A public figure involved with another public figure in a public relationship can expect publicity, not privacy, about why it ends."

Mayweather wants the suit thrown out asap. A judge has yet to rule.

Jordin Sparks may be a damsel in distress ... but now that she's trashed him, she won't be welcome at Jason Derulo's new castle.

Jason bragged about his new medieval digs -- insinuating he doesn't care that Jordin is now trashing him -- by tweeting that he's moved on to bigger and better things: "I bought myself a castle 2day!! No big deal."

Jason isn't directly responding to Jordin's new single in which she essentially calls him an ingrate and an a-hole. But he started it by putting her on blast for allegedly pressuring him to tie the knot.

As for his $3 million acquisition deep in the San Fernando Valley ... it's 10,000 square feet, outfitted with turrets, a dungeon, a basketball/tennis court, and a lap pool -- standard issue for land barons.

It's like Henry VIII moved to Tarzana ... which sounds like a CW show.

Jordin Sparks puts even Taylor Swift to shame by mercilessly going after ex-BF Jason Derulo, calling him out as a vengeful ingrate.

Sparks' SCUD missile takes the form of a mixtape, "#BYEFELICIA," featuring "How Bout Now (Remix)" ... it's a Drake song reworked to rip Derulo.

"Member I deleted all my other guys numbers on my phone for you.
Member when you broke your neck and I had to wash your back for you.
You probably don't remember half the shit that i did for you."

And it goes on ...

"Once you blew up, head got big and you started changing.
Can't believe all the things that you started saying.
Like I'm with you for your fame and your name. What?"

The couple split back in September after a 3-year romance. After the split Jason trashed Jordin, saying she was pressuring him to marry her.

Cops raced to Jose Canseco's Las Vegas home over the weekend after his fiancee called 911 and told police he repeatedly threatened to kill her -- but Jose tells TMZ Sports she's lying through her teeth.

Law enforcement confirms ... Leila Knight called 911 around 11:45 PM on Saturday to report a domestic incident.

Leila tells TMZ Sports ... Jose had flipped out after she dumped him and he "threatened to kill me and my mother." Knight claims he repeated the threat "like 20 times."

Cops rushed to the scene ... and spoke with both Jose and Leila ... but no arrests were made.

We're told cops issued a warning to both parties.

But Jose says Leila is simply spreading lies because he's the one who dumped her ... and she's bitter.

"She's slandering me because I don't want to be with her," Canseco says ... "I fell out of love with her because she's too controlling."

Jose Canseco's engagement is officially OVER ... with Leila Knight telling TMZ Sports she dumped the former MLB star because "he's an a**hole."

One month after he shot himself in the finger ... nearly striking Leila in their Vegas home ... Knight tells us, "I broke up with Jose and am leaving him for good."

Jose has also acknowledged the breakup ... saying, "Leila and I have gone our separate ways. check back later and find out what happened."

So far, the details surrounding the split are unclear ... but Leila is clearly upset -- saying Canseco is an "a**hole" who mistreated her. She also says, "So happy to be single again. Took me a long time to use my brain instead of my heart."

The two got engaged back in 2013 and had been living together in Vegas.

"Entourage" actress Autumn Reeser has just filed for divorce.

It's a familiar Hollywood story -- citing irreconcilable differences as the reason for divorcing Jesse Warren Strutzel. They got married in May 2009 and separated last month.

According to court docs ... Reeser wants joint legal and physical custody of their two young sons -- ages 3 and 11 months, but she's doesn't wanna pay him spousal support.

Strutzel had a web series called "The Bannen Way" ... but Reeser has had the bigger Hollywood career -- starring in TV shows like "The O.C." and "Hawaii 5-0."

Former NBA star Joe Smith claims his ex-girlfriend, "Love & Hip Hollywood" star Moniece Slaughter, bilked him out of a ton of money ... and he's pissed that cops have done nothing about it.

According to a report filed with the Manhattan Beach Police Department, Smith claims that between October 2011 and March 2012, nine checks were written from his checkbook to a Timothy Clayton Carr ... totaling $109,000.

Smith told police he did not write the checks and does not know a man by that name.

In June 2012, police were able to get a hold of Carr, who told them he was a friend of Slaughter and that he was cashing the checks for her as a favor because she didn't have a bank account. Carr told cops he was unaware the checks were stolen or that anything was wrong until Smith canceled the last check.

Carr also told police Slaughter had agreed to pay him back for the canceled check, but it when it came time to meet up ... she disappeared.

But Slaughter told police an entirely different story. According to the report, Slaughter claims Smith knew all about the checks and signed them personally. She claims Smith only canceled the last check because the pair broke up.

After talking to Slaughter, police went back to Smith and explained her story. His response ... "She's crazy."

Smith has told police he wants to press charges, but nearly 2.5 years later ... nothing has come of it. He tells TMZ Sports he's frustrated the case remains unresolved and feels police have been giving him the runaround.

Johnny Weir's ex believes the judge in his divorce case screwed the pooch ... because Johnny has been awarded full custody of their tiny little dog.

And there's more in the bad news department for Victor Voronov ... he doesn't get to keep the $20,000 Faberge egg that was a big bone of contention in their nasty divorce.

We found out Johnny and Victor quietly went to court late last week and the judge laid down the law over some precious items. The Japanese Chin, Tema, was the biggest source of heartache. Victor sobbed back in March, as he watched Weir scoop Tema up and remove her from their home.

The judge also gave Johnny's lawyer permission to sell their wedding rings and the pricey egg to cover legal fees.

Johnny threw a crying fit over the egg -- which led to a 6-hour standoff at their storage facility.

Victor also got shut down in his attempt to get more spousal support, so all he gets is a grand a month.

Why do we think this fight's not over?
