Dating

Melanie Griffith brought a very interesting date to the premiere of her movie "Dark Tourist" this week -- her ex-husband Steven Bauer ... a guy she's BARELY been seen in public with since they divorced more than 20 years ago, TMZ has learned.

Griffith and Bauer (who famously starred in "Scarface" back in 1983) were all over each other on the red carpet ... which raised eyebrows considering Melanie's current husband, Antonio Banderas, was no where to be found.

According to our crack research team, the last time M & S were photographed on a red carpet together was back 1985 ... back when Ronald Reagan was President.

There have been rumors that Melanie and Antonio have been going through a rough patch ... which makes her decision to walk her ex down the red carpet even more curious.

Sources close to the couple tell TMZ ... despite divorcing in 1987, Melanie and Steven have remained close over the years and have worked together to co-parent their son Alexander Bauer, who also attended the premiere.

We reached out to Melanie's people -- but didn't hear anything back.

Sure, Leo DiCaprio might look goofy on the tennis court ... but he doesn't care. Know why?

'Cause his tennis partner is Toni Garrn ... who happens to be a smokin' hot Victoria Secret model ... who Leo probably had sex with after the tennis match on Mallorca.

Advantage: Leo.

Always.

Here comes the bride ... to-be ... at least, that's the way it seemed when Hayden Panettiere arrived to LAX yesterday with a HUGE DIAMOND on her finger.

Rumors have been swirling that the "Nashville" star finally said "Yes" to her massive heavyweight boyfriend Wladimir Klitschko ... but that bling on her hand pretty much put the rumors to bed.

So ... CONGRATS!!!!

Hayden was in a great mood on her way out of the airport yesterday (as usual) -- and there was only one topic to discuss ... weddings! Though it's unclear if she was referencing her own.

Check out the clip.

Simon Cowell's ex-fiancée is doing something rarely seen in Hollywood -- treating his baby news like a bonafide adult because she's actually HAPPY for him ... sources tell TMZ.

After news broke Cowell knocked up Lauren Silverman ... it was reported that his ex-fiancée of two years Mezhgan Hussainy was devastated, thinking it should have been her.

Sources close to Mezhgan tell us, that couldn't be further from the truth. She and Simon have remained close since their split -- they're good friends and talk almost every day.

In fact, Simon told Mezhgan about the baby weeks ago -- and she immediately called Lauren, who she's also friends with, to offer her congrats and support ... knowing how stressful the media attention can be.

Bottom line: she's thrilled for the couple. As long as Simon's happy, she's happy.

That was fast ... Joan Collins has successfully convinced Shirley Jones' publisher that she did NOT nearly have a 4-way orgy with Shirley and their two husbands back in the ''60s -- despite claims in Shirley's new book -- and now, the publisher has agreed to yank the story.

As we reported, Shirley's new book "Shirley Jones: A Memoir" recounts a story about a sex party that nearly went down at Joan Collins' house back in the day -- involving Joan, Shirley, Shirley's husband Jack Cassidy, and Joan's husband Tony Newley.

In the book, Shirley says she declined the orgy invitation ... but Joan says the entire story is bogus, start to finish.

Joan sent Shirley's publisher Simon & Schuster a cease and desist letter after the book was published, demanding a retraction -- and we've learned, both Shirley and the publisher caved ... agreeing to remove Joan's name from the book.

Joan's rep tells us, S&S has agreed to remove Joan's name from Shirley's e-book immediately, as well as in future reprints. As for the books already on shelves, Joan is out of luck.

Emma Roberts is an adult who can take care of herself -- so says the actress' dad Eric Roberts, who tells TMZ, he supports Emma's decision to stay with her BF following her domestic violence arrest this month.

As we reported, Emma was arrested in Montreal July 7th for attacking her boyfriend Evan Peters inside their hotel room, allegedly biting him and even giving him a bloody nose. Emma was eventually released because Evan didn't want to press charges. The two are still together.

But the question: how does Emma's dad feel about that? We asked and he said Emma is a grown-up who can make her own decisions ... as well as her own mistakes, and learn from them. Wise words.

But you've gotta see Eric's reaction to the obvious follow-up question -- would he support Emma MARRYING Evan?

It's a showdown of Selena Gomez' prior suitors.

Here's a topless photo that 20-year-old Nick Jonas shared on his social media page (left) -- and an equally skin-filled photo 19-year-old Justin Bieber posted on his (right).

Sorry gentlemen ... Harry Styles doesn't swing both ways -- at least, he's "pretty sure" he doesn't.

The One Direction singer was talking with British GQ, when he was asked about rumors that he was hooking up with a dude named Nick Grimshaw -- a big TV and radio host in the U.K..

"We're not dating, no. We're just friends," Styles said.

The interviewer pushed the topic a little harder ... saying, "So you're not bisexual?"

To which Harry replied, "Bisexual? Me? I don't think so. I'm pretty sure I'm not."

So, it seems Harry might be straight ... after all, he did recently date Taylor Swift.

... not that there's anything wrong with that.

Emma Roberts got extremely emotional Tuesday, but BF Evan Peters was by her side -- on the heels of news she'd been arrested for a domestic violence incident involving him.

Emma was seen bursting into tears ... as Evan comforted her outside a New Orleans studio.

TMZ broke the story ... Emma was arrested July 7 in Montreal after she and Evan allegedly fought in their hotel room. Police say there was evidence she'd bitten him.

Evan did not want to press charges, and Emma was released.

George Clooney and Stacy Keibler finally broke up like we all knew they would -- the only question is ... HOW did Clooney break it to her?

It was only a matter of time ... but Stacy Keibler's run with George Clooney is officially done.

Sources close to the couple tell TMZ ... the two have broken up after two years of dating.

The couple hasn't been seen together since March and spent the 4th of July on opposite ends of the earth.

Keibler joins a long list of Clooney exes ... which includes Elisabetta Canalis, Kelly Preston, Talia Balsam, Denise Crosby, Celine Balitran, Brooke Langton, Traylor Howard, Lisa Snowdon and Sarah Larson.

In the meantime, here's a clip of Stacy dancing shaking in almost nothing.

Yeah, she's gonna be just fine ...

George Clooney isn't exactly single (yet) ... TMZ has learned he and Stacy Keibler are STILL living together -- despite rumors of a break-up -- BUT an expiration date could be fast approaching.

Multiple reports have surfaced that Clooney and Keibler called it quits after 2 years of dating (which is like a decade in Clooney years). The couple hasn't been seen together since March and spent the 4th of July on opposite ends of the earth.

But sources close to C&K tell TMZ ... the duo is still shacking up, so it's not totally over. However, we're told there's definitely trouble in paradise -- and it's all because of the couple's hectic schedules.

Our sources say George and Stacy haven't been in the same place for months now because she's busy shooting her new show "Supermarket Superstar" and George is busy being a giant movie star.

Hayden Panettiere felt up a statue in Italy this week -- but not just ANY statue -- those boobs belong to JULIET (of Romeo & Juliet) ... and apparently molesting the sculpture is good luck!

It all went down in Verona ... when Hayden and her BF Wladimir Klitschko toured the home where it is believed Juliet lived back in the day ... before she, you know, went all O.J. on herself (allegedly).

During the visit, the couple encountered the famous Juliet statue ... so, naturally, Hayden copped herself a feel. But not because she's a perv -- local legend has it that anyone who rubs J's right breast will be blessed with good fortune.

The ladies LOOOOVE Patrick Schwarzenegger's body ... especially his nipple?

Arnold's 19-year-old kid was hanging out on a yacht in Saint Tropez with his girlfriend Taylor Burns ... when she decided to play the role of male breast inspector.

Meanwhile, over in Hawaii ... Eddie Murphy's girlfriend Paige Butcher rocked another tiny bikini.

Happy summer everyone.

Kanye West insists he did NOT cheat on Kim Kardashian with a Canadian model/bartender -- telling TMZ, the woman accusing him of being unfaithful is just out for some easy publicity.

24-year-old Leyla Ghobadi recently did an interview claiming she met Kanye at one of his concerts in July 2012 -- three months after Kim and Kanye began dating. She says Kanye had his security pick her out of the crowd and they went for drinks after.

She claims they later engaged in two sexual encounters -- one while Kim was pregnant -- and that Kanye confessed his relationship to Kim was a sham in order to increase his fan base.

But a rep for Kanye says it's all BS -- telling us, "This most recent attack on Kanye West and his family is totally without merit. It's a blatant attempt by a misguided individual who is clearly seeking publicity, and another in a series of malicious stories drummed up by non-credible 'news' sources."

The rep adds, "This is a sad attempt to hurt two people trying to live their lives."

Zooey Deschanel played the role of caring girlfriend this week ... when her boyfriend was wheeled out of an L.A. hospital with bandages all over his face ... but don't worry, he's gonna be fine.

The "New Girl" star helped her screenwriter BF Jamie Linden out of his wheelchair and into a waiting Tesla outside of the hospital Tuesday ... sparking concern that something was seriously wrong.

But Zooey's rep tells TMZ it looks worse than it is -- explaining, "Jamie had a very minor and routine sinus procedure done, all is well."

Now we can all breathe easier ... especially Jamie.
