Breakups

Courtney Robertson is about $80k lighter today -- because "The Bachelor" winner finally returned her diamond engagement ring to its rightful owner ... and photogs caught every glorious moment of it.

Robertson -- who called it quits with "Bachelor" Ben Flajnik last week -- hit up a Neil Lane jewelry store in L.A. Sunday to say sayonara to the 3-carat rock.

We're told the ring ended up back at Neil Lane since "Bachelors" and "Bachelorettes" don't foot the bill for their own marital swag -- i.e. when the relationship goes away, so does the bling.

But Court's not shedding too many tears over the loss (of the ring or Ben) -- considering she was recently seen sucking face with "Bachelorette" cast-off Arie Luyendyk Jr.

Ah, love.

Courtney Robertson is one helluva rebounder ... 'cause days after she split from "Bachelor" Ben Flajnik ... she was TOTALLY MAKING OUT with one of the rejects from "The Bachelorette."

TMZ obtained pics of Courtney sucking face with Arie Luyendyk Jr. -- who took 2nd place on last season's "Bachelorette" when he was shot down by Emily Maynard.

Of course, Courtney was SUPPOSED to marry Ben after he picked her on the "Bachelor" finale earlier this year ... but they split last week claiming things just weren't working out.

But it didn't take long for Court to move on ... 'cause Thursday night, she and Arie had dinner together at the fancy Quiessence Restaurant in Phoenix -- and we're told they were all over each other the whole time.

Just one day after news broke of her split from longtime husband Danny DeVito, "Cheers" star Rhea Perlman stepped out in L.A. today sans wedding ring -- with a big ol' smirk on her face.

As we previously reported, 67-year-old Danny and 64-year-old Rhea are separating after 30 years of marriage. The reason for the split is still unclear.

The news came as a shock even to close friends. In fact, "Cheers" actor John Ratzenberger said he saw Rhea just the other day and she never suggested things were going south in her marriage.

Danny DeVito and Rhea Perlman's split didn't just come as a surprise to their fans ... it also blindsided their close friends -- including "Cheers" actor John Ratzenberger, who claims he had NO IDEA the famed couple was calling it quits.

Ratzenberger -- who played Cliff on the 80s sitcom alongside Rhea -- said he just saw his old co-star the other day and she didn't even suggest things were going south with her husband of 30 years.

Danny DeVito and Rhea Perlman are separating after 30 years of marriage.

The two married back in 1982 and have 3 children together.

DeVito (5'0") and Perlman (5'1") met in 1970 when Rhea went to see an off-Broadway play, The Shrinking Bride ... which featured Danny.

The two began dating soon after and lived together for 11 years before tying the knot.

A rep for the couple confirmed the split -- but has no further comment at this time.

She's single ... and it appears Chris Brown's ex-GF is ready to mingle -- 'cause Karrueche Tran hit up the L.A. club scene this weekend on a serious girls' night out.

Tran and two of her girlfriends rolled up to Greystone Manor in Hollywood in a tricked out blue Porsche Panamera shortly after midnight Monday morning.

As we previously reported, Tran was pissed when she saw Brown's bizarre breakup video statement ... in which he questioned if it's possible to love two people at once.

Chris Brown's recently axed ex-girlfriend has 3 words for him -- shut your mouth ... because she is PISSED C.B. made that highly-produced drunken video confession about loving two chicks.

Sources close to Karrueche Tran tell TMZ ... she's livid over the fact that Brown blasted their personal problems all over the internet with his ridiculous video -- in which he confesses to loving Rihanna and Karrueche at the same time.

If Chris thought the video would soften the blow of breaking up with Karrueche ... he was dead wrong. We're told KT feels Brown should have kept his feelings private and she's disappointed and hurt by his decision to broadcast their personal life.

As TMZ previously reported ... Brown announced his split from Karrueche earlier this week by stating, "I love Karrueche very much but I don't want to see her hurt over my friendship with Rihanna."

He later posted this video, claiming he has feelings for both ...

Chris Brown dumped his girlfriend Karrueche for Rihanna, then immediately said he's still in love with both of them. Can Chris have his Rihanna and eat it too? We gotta ask ...

Chris Brown just released a hyper-produced propaganda break-up video ... in which he drunkenly says he loves BOTH Rihanna and his ex-GF Karrueche Tran ... and says, "I'm not trying to be a player ... I just care too much sometimes."

It seems to be an artsy-fartsy way to explain his decision to kick Karrueche to the curb after being seen with Rihanna this week.

In the footage, Brown tries to hammer home the point that he's wasted -- intercutting footage of himself poppin' champagne, partying in a nightclub and looking slouched over while smoking. At one point he says, "I'm a little drunk, so I'mma be honest ..."

It's unclear when the footage was shot ... but two hours before Brown posted the video, Rihanna tweeted, "Ain't nobody bidness..... But mine and my baby!"

He never mentions either woman by name in the video, but there are shots of both RiRi and Karrueche spliced into the 1:27 clip.

Chris Brown and Rihanna got real -- like REAL real -- by getting cuddly at Jay-Z's concert! Then Chris got REAL by dumping his GF!! Too REAL, right?

Brown announced this morning that he kicked his GF Karrueche Tran to the curb because he wants to concentrate on his "friendship" with Rihanna ... and by "friendship" he means he's going to take her to Bone Town.

Chris Brown's ex-girlfriend ain't buyin' that Chris is "just friends" with Rihanna ... telling her peeps she's convinced they were bangin' behind her back.

We spoke to multiple sources connected to Karrueche Tran ... who tell us KT feels betrayed by Chris because he had promised her that she was the only woman in his life ... especially when she probed him about his feelings toward Rihanna.

We're told Karrueche had suspected something was up between the two of them for weeks because Chris was acting differently -- going to clubs alone, acting distant and ramping up his public appearances with Rihanna.

Sources say Karrueche told friends she truly loved Chris ... and felt that the relationship was great until Rihanna let Brown back into her life.

Chris Brown says he has officially BROKEN UP with his girlfriend Karrueche Tran ... explaining, "I don't want to see her hurt over my friendship with Rihanna."

Brown just made the announcement ... saying, "I have decided to be single to focus on my career. I love Karrueche very much but I don't want to see her hurt over my friendship with Rihanna."

He adds, "I'd rather be single allowing us to both be happy in our lives."

The announcement comes after Brown and Rihanna were spotted together at the Jay Z concert in Brooklyn last night. The two had been hanging around each other A LOT lately ... and did some hardcore flirting at the MTV VMAs.

Karrueche had posted a cryptic tweet last night reading, "Bye baby."

Rihanna and Chris Brown aren't even trying to hide it anymore -- 'cause it looks like they were getting cozy at the Jay-Z concert tonight ... and, based on Twitter, everyone in Brooklyn saw it.

A pic taken from behind RiRi and Chris at Barclays Center is burning up the Internet -- they're seated in VIP ... he's on the left, she's on the right.

No physical contact -- in the photo, anyway -- but Chris' right arm is stretched around the back of Rihanna's chair.

This reunion comes the night after Chris and Rihanna were spotted at the same table in an NYC nightclub.

They were also seen leaving the same hotel on Wednesday -- and, for what it's worth, Chris' blind-as-a-bat GF Karrueche tweeted "Bye baby" ... just a couple hours before tonight's concert.

Apparently, Jay-Z is so powerful he can turn back time ... to 2008.

Arnold Schwarzenegger is out hawking his autobiography, so he knows something about words ... and the one word he WON'T use to describe his affair with the maid is "BETRAYAL."

In an interview on "60 Minutes" which will air Sunday, Lesley Stahl said to Arnold ...

"She gave up her television career for you. I mean, wow, was this the most unbelievable act of betrayal to Maria?"

Arnold would not acknowledge Stahl's question. Instead he deflected by saying, "I think it was the stupidest thing I've done in the whole relationship. It was terrible I inflicted tremendous pain on Maria and unbelievable pain on the kids."

And it's even worse. Arnold has not even shown the book to Maria. When Stahl asked if she knew what Arnold had written, all he would say was, "She knows that it's about my whole life."

Two months after announcing the end of her relationship with Johnny Depp, French singer/actress Vanessa Paradis soaked her sexy bones in a black bikini while vacationing in Corsica the other day.

In June, Vanessa and Johnny split up after 14 years -- and having two children -- together.
