Breakups

8:47 A.M. PDT -- We're told the game was a Roc Nation charity event. Rihanna was scheduled to be there and Chris was supposedly a "surprise appearance."

Rihanna is ridiculous ... and thirsty like Moses wandering the desert.

She showed up in the front row at a charity basketball game Thursday ... eyes trained on ex-BF Chris Brown.

Now that she's with Drake again and not Chris Brown again ... you'd think she wouldn't fuel the fire. But then again, who are we kidding?

It's a special kind of insult to Karrueche ... who's back with Chris after being repeatedly humiliated by whatever continues to transpire between him and Rihanna.

Your move Karrueche.

Mariah Carey has gagged Nick Cannon -- but not in a good way. He's not allowed to say boo about their divorce ... or else.

Sources close to the couple tell TMZ ... Nick and Mariah's lawyers hashed out a confidentiality agreement as part of their divorce ... and it's completely one-sided.

Nick is barred from saying anything about the split. If he does, there are severe financial penalties. But Mariah has the right under the agreement to announce the split on her terms.

Nick is clearly following orders ... check out the video from NYC Thursday -- he zipped it.

Nick is allowed to say they're now living separately ... which he's already done. But he cannot say anything about the divorce.

As TMZ first reported ... the divorce is a "done deal" ... the property settlement and child custody have already been hashed out.

Nick Cannon took the first public shot at his estranged wife Mariah Carey ... by putting his soon-to-be single body on display ... for the sake of charity of course.

TMZ broke the story ... the couple's divorce is a "done deal." Nick is clearly telegraphing ... he's taking the split in stride.

Cannon accepted the ALS Ice Bucket Challenge from Spice Girl Mel B and upped the ante by completing the task in the BUFF!

Nick also makes a point of talking about his wiener ... fond memories, Mariah?

Our sources say ... Nick's appearance on Big Boy's radio show in March was the beginning of the end. Nick played Big Boy's game -- name the 5 celebs you've slept with. Nick named 5, but our sources say the one that made Mariah insane was Kim Kardashian.

We're told Mariah tore into Nick for weeks ... feeling humiliated and the relationship never recovered.

We're told it went from bad to worse when Nick went on Howard Stern and talked about Mariah not giving it up before they got hitched. She went nuclear.

Our sources say Mariah feels Nick has abandoned her by taking every gig that's on the table ... when they don't need the money. She's especially angry because it keeps him away from their kids.

For Nick's part ... we're told he feels Mariah has become impossible because she surrounds herself with "yes men." He says she can't handle it when he dares to disagree with her.

We're also told Nick is incredulous Mariah is bitching about his work ethic ... he says he's generated $75 million since 2011 for the family.

Taylor Swift and John Mayer showed up at the same place Wednesday night ... eating dinner within eyeshot of each other ... and we know what didn't happen.

We got pics of Swift and Mayer leaving Chateau Marmont in West Hollywood in separate cars ... so there's smoke.

But there's no fire. Our Chateau spies say John and Taylor saw each other but didn't exchange a single word.

They famously dated a few years ago and traded breakup songs about their relationship.

Beyonce and Jay Z are NOT breaking up ... in fact, their relationship is "perfect' ... so says a woman who would definitely know -- Beyonce's mom.

Tina Knowles was leaving lunch with Kelly Rowland at Via Alloro in Bev Hills -- and in a super-rare moment, actually opened up about rumors that B and J's marriage is on the rocks.

Mama Knowles even had some choice words for people like Akon -- who recently told us the couple's relationship "feels corporate."

Kevin Hart's ex-wife Torrei has her own life, her own money, her own career ... and she's OVER Kevin Hart ... so she says.

Our photog got the "Atlanta Exes" star at LAX Wednesday ... as she pimped her new line of mixers, she insisted she was not bent out of shape when Kevin and his freshly-minted fiancee came face-to-face with her at Magic City strip club in ATL Monday ... where Kev dropped $40K.

Good Q by our photog -- If Kevin invites her to the wedding, would she go?

Robin Thicke is living that bachelor life now, which includes making a solo run to the grocery store Tuesday.

Robin went to the uber-expensive Bristol Farms in Bev Hills ... where 3 bags of groceries can really set you back. And, just like the rest of us, he succumbed to the temptation of tortilla chips.

Kevin Hart was eye to eye with his ex-wife at Magic City strip club in ATL ... hours after he popped the question to Eniko Parrish.

Kevin and ex-wife Torrei Hart seemed at odds Monday night ... her show -- "Atlanta Exes" -- had its premiere, where she accused Kevin of cheating on her. For his part, Kevin jacked her spotlight by proposing to his fiancee and then posted the video on Instagram.

So Torrei took her co-stars to the strip club after the show aired ... and around midnight Kevin walked in with his freshly-minted fiancee.

It gets better ... we're told the 2 exes were seated within eyeshot of each other. They noticed each other but didn't say a word to one another.

But Kevin made a big statement -- he dropped $40K with his fiancee ... making it rain all over the place.

Torrei sat impassively ... with her new guy.

Happy ending.

So Drake and Rihanna walk into a club ... which means they were banging, right?

The former couple hit up Griffin nightclub in NYC Monday night ... and according to photogs they were there for nearly 2 hours and left at around 3 AM -- 21 minutes apart.

Eyewitnesses inside the club tell TMZ ... Drake and Rihanna had tables next to each other and were deep in conversation, flirtatious and whispering in each other's ears.

Jennifer Lopez and Casper Smart were back together Monday ... and when she spotted the photog she ducked for cover -- which totally means they're banging!

We think it's JLo's car ... it's definitely not his, although he's driving.

JLo and Casper broke up in June after dating 2 1/2 years. There were reports Smart cheated on JLo with a transsexual, but he denied it and threatened to sue.

As we reported ... the breakup was amicable and they parted as friends. Now it appears there may be benefits to the friendship.

Audrina Patridge is on the market again after 5 years with BMX biker Corey Bohan ... but retired NFL stars apparently aren't part of her rebound plan.

Audrina was at LAX giving us some relationship advice when a recently minted NFL Hall of Famer just happened to stroll by ... which got our cameraman thinking he'd be the perfect rebound guy.

We'll let you see how the encounter played out ... but suffice to say she's still available

Poor Sapp ... look what he's missing out on.

Chris Brown says he's back with Karrueche because she finally realized he did NOT have sex on a St. Tropez yacht.

The on-again-off-again couple is now on again ... and Chris says it's because Karrueche now realizes he was telling her the truth when he said he was not having sex with anyone else.

Sources close to Karrueche tell us ... he was frantically texting and calling her -- more than 20 attempts a day -- to acquit himself, but she ignored him.

We're told Saturday ... Karrueche showed up at Chris' celebrity flag football game to talk it out ... which they did, and she believes him.

As for the whole yacht thing ... there definitely was smoke ... he was on the vessel cavorting with several women, including one of Karrueche's close friends.

Antonio Banderas is single and ready to mingle ... and he zeroed in on an attractive woman while partying in St. Tropez over the weekend.

Chris Brown and Karrueche Tran prove ... there really is a fine line between love and hate ... because it seems they're back together.

They two got super handsy Saturday at a charity football game in L.A.

Just days ago Karrueche had nothing but bad things to say about Chris -- and sources close to Brown painted an equally unflattering pic of the relationship.

We also got the former couple leaving the game ... and once again, Chris was openly affectionate.

Michael and Nicole, Justin and Selena, Chris and Karrueche ... maybe this is the secret to a long relationship.

Katharine McPhee can't keep her hands off her co-workers ... but it's not a director this time ... it's her new show's leading man.

McPhee was on set Thursday getting handsy with Elyes Gabel, her co-star in the upcoming CBS series, "Scorpion." Unlike her last on-set romance ... Gabel's not married and she's getting divorced.

You'll remember ... photos surfaced of McPhee locking lips with "Smash" director Michael Morris in October 2013. McPhee was married to Nick Cokas (though she claims they were separated) and Morris was married to actress Mary McCormack (they're still together).

Her next project will be interesting ... what the hell will she do if she co-stars with Neil Patrick Harris?
