Breakups

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?

Michael Strahan and Nicole Murphy had lunch together Thursday in Beverly Hills ... and our sources say there's "a possibility" of getting back together.

Michael and Nicole went to South Beverly Grill. They walked out arm-in-arm. Sources connected with the former couple tell us ... they both still have love for each other and, as one source says they'd "like to work things out."

Another source was more guarded, saying, "It was a friendly lunch. They have 7 years of history together."

Michael seemed stunned on his way out when our photog tried to get a debrief. And much to Michael's dismay, the restaurant has one of the worst, most congested parking lots in Bev Hills, so our guy peppered him with questions as he waited, including, "Who paid for lunch?"

Porn star Christy Mack and War Machine were still close enough 20 days ago that they were holding hands in public at an MMA fight.

TMZ obtained the pic taken in Temecula, CA while they were attending the fight ... and their coziness seems to contradict Christy's initial claim that they've been broken up for several months.

Christy's family and friends tell us although the pair "officially" broke up in May ... they still consistently hooked up from time to time. The pic may explain War Machine getting jealous of Christy's new boyfriend Corey Thomas.

Two of the hottest couples in hip hopdom -- Tyga and Black Chyna … and Ciara and Future … are both kaput. It might be just a coincidence.

But it's more likely they fell victim to the most hazardous time of the year … for baby mamas everywhere.

Ramona Singer -- who stars in "Real Housewives of New York City" -- has gone to the NYPD ... claiming her estranged husband's mistress has been stalking her ... TMZ has learned.

Law enforcement sources tell us ... Ramona called 911 Wednesday afternoon, claiming the woman had followed her to a restaurant.

Ramona revealed last week she was leaving hubby Mario Singer, although she didn't say why. Other members of the cast dimed Mario to the media ... at least they alleged he was cheating.

But now we know ... Singer herself believes Mario was cheating, and for some reason she believes the mistress is obsessed with her.

Future and Ciara are done for good ... the engagement is off and they are officially single ... sources connected with the former couple tell TMZ.

Ciara is the one who did the breaking up ... she claims he was cheating on her while on tour.

It's complicated ... because they have a 3-month-old son, Future Zahir. We're told she has the kid and fully intends to get custody.

As for Future's response to Ciara's allegations ... so far he's radio silent.

Katharine McPhee's hubby claims his estranged wife is a cheater and a liar.

Nick Cokas has filed new divorce docs -- obtained by TMZ -- which squarely contradict Katharine's version of the timeline of their separation ... which is relevant because of the photos showing her making out with "Smash" director Michael Morris.

Katharine claimed in her divorce docs they separated in March, 2013 -- months before pics surfaced in October showing Katharine and Michael sucking face.

But Nick begs to differ, claiming the separation was actually in May, 2014 ... long after Katharine hooked up with Michael.

Nick has some pretty powerful evidence to back up his version, including emails and texts about their relationship. Family sources say Nick can show he and Katharine were in marriage counseling AFTER the pictures surfaced.

The separation date is important because it determines when Katharine's money becomes hers alone.

Porn star Christy Mack is strapped for cash because she needs major reconstructive surgery after being beaten by ex-BF War Machine ... but her fellow porn stars have come to the rescue.

Adult actress Kendall Karson has launched a crowdfunding campaign to raise money so Christy can be pretty again. So far she's raised $30K to help pay for the cost of repairing her nose, eye socket and various other procedures. The goal is $100K.

In addition to Kendall, Kendra Lust, Ava Addams and Tasha Reign have donated money ... and so has Dave Navarro. Jenna Jameson has also given her support.

And the kind folks at Brazzers.com have pitched in $10K.
