Hook Ups

Michael Phelps is a 27-year-old, newly-single Olympic hero ... so it should be surprising to no one that he's flirting with hot chicks less than two weeks after his break up.

As TMZ first reported, Phelps split from the super-hot Megan Rossee just before the New Year.

According to our sources, Phelps (still sporting the porn stache) was hanging poolside on Friday, smoking cigars with his friends and macking on the girl in the yellow shirt.

Demi Moore and Harry Morton are definitely NOT dating ... or banging ... or boning ... or doing the deed ... despite multiple reports to the contrary.

Reports have been circulating lately that Demi found herself a post-Ashton boy toy in the form of Pink Taco head honcho (and Lindsay Lohan's ex) Harry Morton. The reports claim the two have been on several dates in the past few weeks.

But it just ain't so. According to our sources, the two are NOT together. We're told they've been friends for a long time and they did go to dinner Wednesday night in Beverly Hills, but it was in NO WAY romantic.

Our sources say the duo have a slew of mutual friends, so they see each other a lot. We're told neither party is ruling out the possibility of dating in the future -- but right now, it's strictly a platonic thing.

James Deen sounds like a man with a secret ... 'cause when we asked "The Canyons" star if he ever hooked up with his co-star Lindsay Lohan on the set of the film ... he didn't say "No."

Deen called in to "TMZ Live" on Friday to discuss Lindsay's on-set tirade directed at him ... when we asked if the argument could've stemmed from sexual tension.

After all ... it's not uncommon for a leading man to sleep with his leading lady ... especially when the leading man is a very active, very "talented" porn star.

It's barely been a month since she broke up with her NFL player ex, but Hayden Panettiere's already got her hands on another man's kielbasa ... ex-BF Wladimir Klitschko ... at least that's the way it seemed at the airport today ... with her adorably girly giggle fit.

Fact: the 6'6" Ukrainian World Boxing Organization champ dropped 5'2" Hayden off at the airport today in Florida, where he lives.

Fact: When Hayden landed in L.A. she giggled like a schoolgirl when we asked her about Wlad -- insisting she and Wlad are "just good buddies."

Fact: THEY'RE OBVIOUSLY BONING AGAIN ... probably.

You'll recall, Hayden and her ex-BF Scotty McKnight -- who played for the Jets before he was cut last summer -- called it quits back in December.

Nicki Minaj has a new man, and the undeniable proof is ... missing. But we do have this video -- which is 100% partial evidence ... that she left a restaurant!! See? Totally banging a new bf.

For the first time ever, Kathy Griffin might actually have a good point -- telling TMZ, of course she tried to kiss Anderson Cooper's penis on New Year's ... because who wouldn't??? IT'S ANDERSON COOPER!!!

Kathy was out in NYC yesterday -- with her boyfriend -- when we asked about her infamous penis-smooching escapade while hosting the New Year's Eve countdown on CNN with Anderson Cooper.

Kathy didn't try to minimize it either, telling us, "I've hit on [Anderson] many times."

It must be his laugh.

Leonardo DiCaprio and Jonah Hill spent the holidays with a boatload of the hottest women on Earth -- which can only mean one thing ... Leo gets first dibs. The bright side ... Leo's leftovers are all 10s.

And just like that ... Rihanna's back where it all started ... Chris Brown's passenger seat.

The on-again couple relived their past earlier today in L.A., where they picked up some refreshments -- including an Icee -- at a gas station convenience store.

You'll recall, Rihanna was riding shotgun back in 2009 when CB unleashed a ferocious beatdown on her face -- but today, she was nothing but smiles.

Oh yeah, that red sweatshirt she's wearing is Chris' clothing line -- Black Pyramid.

Hope Part 2 works out better.

President Obama got down with the First Lady -- mouthing the lyrics to a classic, and filthy, Led Zeppelin song during the Kennedy Center Honors ... and it might be the most badass move a Prez ever made.

Barack got his pimp on while Lenny Kravitz sang "Whole Lotta Love" as a tribute to the surviving members of Zep ... who were hailed during the KCH that aired last night.

While Lenny was jamming the camera cut away to the Prez and Michelle Obama a couple of times ... including once when Barack lip synched the chorus, "want a whole lotta love."

Interestingly, there was no cutaway to the First Couple during the following lyric:
- I'm gonna give you every inch of my love, gonna give you my love

Or ...
- Shake for me, girl. I wanna be your backdoor man.

Russell Simmons could teach Halle Berry a thing or two about breaking up. He's on such good terms with ex-wife Kimora Lee, he kicked it with her AND new GF Hana Nitsche Wednesday on the beach in St. Barths.

Simmons and Kimora Lee divorced in 2009 ... but they stayed unusually and refreshingly close post-split ... sometimes vacationing together with their respective SOs.

There's no question Russell can pull some impressive ass -- but we gotta ask ...

Chris Brown and Rihanna put on one helluva romantic show for fans during their Laker game PDA -- but seeing it was very upsetting to one TMZ staffer ... one whiny TMZ staffer.

Is your marriage going soft? Well you're in luck, because President Barack Obama's got some tips for keeping things spicy with your significant other.

Barack and his wife Michelle sat for an interview with Barbara Walters recently, when Barbara asked how the couple "keeps the fire going."

Barack laughed, then replied, "We've been married now twenty years, and like every marriage you have your ups and you have your downs, but if you work through the tough times the respect and love that you feel deepens."

For the first time in YEARS, Chris Brown and Rihanna arrived at a public event TOGETHER -- sitting side-by-side at the Lakers vs. Knicks game at Staples Center.

The two arrived to the arena in the same car earlier today, but got out of the vehicle separately. They eventually met up inside and sat down together in their courtside seats.

Chris and Rihanna haven't officially announced they're back on -- but it sure as hell seems like it ... especially with Chris dumping his old GF Karrueche Tran over his undying "love" for RiRi.

Ashton Kutcher is gettin' super serious with Mila Kunis ... or so it seems ... 'cause just days after he filed for divorce from Demi Moore, he took Mila to spend Xmas with his fam ... in Iowa.

Ashton and Mila were spotted in Kutcher's home town of Cedar Rapids this weekend, munching down on some Fro Yo at a local shop ... this according to People.com.

The timing is interesting -- considering the actor JUST filed his divorce papers last week, more than a year after he and Demi split up. It appears Ashton's trying to clear the decks for his newer, younger, more exciting relationship.

Who KNOWS where his mouth's been??? At least that's Lindsay Lohan's explanation for shutting down a "Scary Movie 5" kissing scene between her and Charlie Sheen -- saying she refused to lock lips with him in the movie because of his spotty history.

Sources close to Lindsay tell TMZ, she was supposed to kiss Charlie three times during their "Scary Movie" bedroom scene, but she ultimately refused to do it because of Charlie's wild partying past.

It's unclear what Lindsay was so paranoid about -- but we're told BOTH parties had to sign releases that they didn't have cold sores.

Lindsay's telling friends she warned producers ahead of time that she had issues with kissing Charlie -- who's had considerable dental work done in the last couple years -- but they didn't change the script until it was time to shoot the scene.

According to sources, Charlie was cool as a cucumber about the whole thing, and never voiced any concerns with the rewrite ... or Lindsay's objections.

In fact, as we first reported, Charlie eventually gave Lindsay $100,000 to help pay off her taxes.

They say a picture's worth a thousand words ... and if that picture happens to feature a penis that was FRACTURED during sex, it might be worth a couple thousand bucks ... at least that's what MMA fighter Ray Elbe is hoping for.

Sources close to Elbe tell TMZ ... the former "Ultimate Fighter" contestant TOOK PHOTOS of his mangled manhood after his GF snapped it in half during a spirited love-making session.

As we previously reported, Elbe's penis ripped open ... sending blood spattering all over his room. He was rushed to a nearby hospital where he was immediately stitched up.
