Hook Ups

Chris Brown and Rihanna are barely trying to hide it anymore -- getting up close and personal at a NYC nightclub late Monday night ... then carousing at Rihanna's hotel for hours.

Chris and Rihanna hit up Griffin nightclub in the Meatpacking District -- we're told they arrived 5 minutes apart, and quickly ended up at the same table. Sources inside the club say the two were all over each other, and even disappeared together in a bathroom for 20 minutes.

People inside the club say the duo were kissing and hugging out in the open.

The two left the club separately -- but hours later, Chris was spotted leaving the Gansevoort Hotel, where Rihanna was staying.

By the way, Tuesday afternoon, Chris' clueless GF Karrueche tweeted that Chris sent her roses, a teddy bear and chocolates -- maybe a lame, "I'm sorry."

So we gotta ask ...

Minka Kelly and Chris Evans proved they're more than just friends by swapping spit outside a restaurant in Studio City on Monday.

The sexy couple -- who dated briefly in 2007 -- have been spotted hanging out together in recent weeks, but this is the first time they've gotten hot and heavy in public.

Prior to hooking up with Captain America, 32-year-old Minka broke up with her longtime NY Yankee boyfriend Derek Jeter last year.

She really knows how to play the field.

Brittany Kerr has issued an apology for getting up close and personal with married country singer Jason Aldean ... chalking the whole thing up to a "lapse in judgment."

The former "American Idol" contestant says, "The actions I portrayed recently were not a representation of my true character, but a lapse in judgment on my part."

She adds, "I would like to sincerely apologize to everyone that has been affected by this, including my friends & family."

We broke the story ... Aldean put the moves on Kerr on the patio of a crowded bar on the Sunset Strip last week. Jason later issued an apology ... saying the whole thing was a drunken mistake.

Here's the question/inconsistency. Brittany told friends after we first posted the pics that she didn't know Jason was married. So, if she did know ... why does she now say she had a "lapse in judgment?" Just asking.

Money and fame doesn't always lead to bangin' more chicks ... at least according to "Joe Millionaire" Evan Marriott ... who tells TMZ he used to get laid more frequently BEFORE he became a celebrity.

The former reality TV superstar -- now 38-years-old -- was leaving LAX last night when he told us he's back in the construction biz ... and still on the hunt for a Mrs. Millionaire.

Evan says the show had a massive impact on his life (he reportedly made somewhere in the neighborhood of $2.5 million from projects related to the "Millionaire") ... but says the experience definitely had a negative affect on his booty intake.

As for Zora -- the girl Evan picked to split the show's million-dollar prize -- he says he hasn't spoken to her in YEARS.

Jason Aldean wasn't lying ... the married country star WAS a drunken mess on that night he macked on "American Idol" contestant Brittany Kerr ... and TMZ has the video that proves it.

We shot the footage last week ... showing Aldean and some of his buddies stumbling out of "The Den" bar and grill on the Sunset Strip and into a waiting taxi.

At the time, we had no idea the guy had been making out with the "Idol" singer ... we just knew he was hammered ... so, nothing special.

FYI -- you can plainly see Aldean's wedding ring in the video ... so Kerr's excuse that she didn't know he was married is dubious.

Former "American Idol" contestant Brittany Kerr has shut down her Twitter page ... after a gang of angry Jason Aldean fans BLASTED the singer online -- calling her everything from a "skank" to a "homewrecking whore."

The cyber-hate came flooding in after TMZ posted the pics of Aldean -- a huge country singer who happens to be MARRIED -- putting the moves on Kerr at a crowded bar on the Sunset Strip.

Sources connected to Kerr tell us ... she had NO IDEA Aldean was married ... and if she would have known, she would have shut the whole thing down from the start.

Even though Kerr didn't go home with Aldean, people attacked her online ... writing terrible things on her Facebook page including:

"Disgusting homewrecking tramp!"

"what is wrong with you taking advantage of a married man while he was drinking."

For the record, people have ripped Aldean on his Facebook page too. He has since apologized, chalking the whole thing up to a bad drunken decision.

Country music superstar Jason Aldean says his very open public display of affection with a former "American Idol" contestant -- who is NOT his wife -- was a huge, drunken mistake.

Jason released a statement today, apologizing for his indiscretion, after TMZ posted pictures early this morning of the country singer and "A.I." castoff Brittany Kerr getting up close and personal -- hugging, touching, and flirting at a very popular, crowded bar on the Sunset Strip (above).

Jason -- who has been married since 2001 -- says, "The truth is that I screwed up. I had too much to drink, let the party get out of hand and acted inappropriately at a bar."

He says, "I ultimately ended up embarrassing my family and myself." And then adds, "I left alone and that's the end of the story."

Country music superstar Jason Aldean got up close and personal with a former "A.I" contestant ... right in the open at a very public bar on the Sunset Strip. There's just one problem ... he's married to another woman.

TMZ obtained photos of Jason and Season 11 "A.I" contender Brittany Kerr taken on the crowded bar patio area at The Den on Wednesday night -- frequented by locals and tourists always on the hunt for celebrities.

In the photos Aldean and Kerr get very flirty ... hugging, touching each other and at one point it appears Aldean goes in for a kiss.

Aldean --- who performed this weekend in So Cal -- eventually left the bar in a cab without Brittany.

Here's the rub, Aldean is married to his high school sweetheart, Jessica Ussery, who he tied the knot with back in 2001 and they have 2 kids together.

Philandering film star Arnold Schwarzenegger has finally admitted to having an affair with actress Brigitte Nielsen -- while still dating Maria Shriver. Well, at least she's hotter than the maid.

Schwarzenegger cops to the sexual tryst in his new book, saying it went down while the duo was filming "Red Sonja" together back in 1985.

At the time of the affair, Arnold was already knee deep into his relationship with Shriver -- and even though they weren't married, the couple was living together.

If you recall ... Nielsen blew the whistle on the affair last year in her own published memoirs. Arnold never confirmed it -- until now.

Nicole Scherzinger insists ... she did not swap spit with Chris Brown last night inside a Hollywood nightclub -- telling TMZ, the two were simply talking ... very closely.

In case you haven't already seen the photos -- they show Chris and Nicole inside Supperclub last night getting very close to each other. According to reports, the two were even making out ... and some people think the above photo is proof.

But a rep for the ex-Pussycat Doll tells us, "There is absolutely no truth to the ridiculous story ... The photos that have surfaced are old friends who were trying to talk at a very loud club."

The rep adds, "I guarantee there will be no photos of them kissing."

Call him Ass Ventura.

Jim Carrey hit the beach in Malibu this weekend with a brand new thongtastic bikini chick ... just a short time after reportedly breaking things off with his last GF -- 23-year-old Anastasia Vitkina.

50-year-old Carrey is a LEGEND on the Hollywood dating scene ... cycling through stunners like Jenny McCarthy, January Jones, Renee Zellweger and Lauren Holly.

Heidi Klum and her bodyguard/boyfriend Martin Kirsten were spotted this morning leaving the Beverly Hills Hotel after having breakfast together.

Heidi told Katie Couric this week that the two are "seeing" each other -- but despite Seal's claims, the relationship began after she split from him.

On her last trip to NYC, Heidi used a different bodyguard, giving her man the day off.

Yeah, Mark Sanchez and Eva Longoria are definitely doing it.

The freshly-minted couple left the Ritz-Carlton in NYC for a late night dinner at the uber-fancy French restaurant Daniel.

The New York Jets QB is 25 -- she's 37.

Having just divorced another professional athlete -- NBA star Tony Parker -- Eva's clearly got a thing. As for Sanchez, he was previously banging 20-year-old Kate Upton.

So we gotta ask ...

Stacy Keibler doused herself in George Clooney repellent yesterday, trying on a giant yellow diamond ring designed by Jacob Arabo ... aka Jacob the Jeweler, jeweler of the stars.

Clooney, the world's most infamous bachelor, has long maintained he will never get married again (he was married for a few years to actress Talia Balsam).

His last girlfriend, Elisabetta Canalis, told an Italian magazine in 2009 that she hoped to be a bride someday. Less than two weeks later, they broke up.

A source close to Stacy says don't read too much into the pics -- it was just an event, and Stacy was asked by Jacob to wear the ring.

But on her left hand?

Kris Humphries and his on-again girlfriend Myla Sinanaj are so chummy ... the NBA star actually gave Myla his ridiculously expensive Mercedes-Benz -- at least for now.

Myla arrived home to her house today in Rutherford, NJ driving Kris' white Mercedes -- and we KNOW it's his Mercedes because he's been driving the same car forever ... long before Myla even entered the picture.

We asked Myla what she was doing in the whip, and she insisted, "It's my car. It's not his car."

Which means she's either bending the truth, or Kris actually gave her the ride. In either case, it's obvious things are heating up between the two.

Nevertheless, Myla says, "We're just friends, hanging out."

Director Nick Cassavetes tells TMZ, he isn't a politician ... he's an artist who makes movies -- and that's why his comments about brother-sister lovin' won't have a damned effect on his career.

As we previously reported, Nick recently spoke out in defense of ALL kinds of relationships while promoting his new film in Toronto this weekend -- gay, straight, incestuous, whatever -- saying, "Who gives a s**t if people judge you? I'm not saying this is an absolute but in a way, if you're not having kids -- who gives a damn?"

He continued, "If it’s your brother or sister it’s super-weird, but if you look at it, you’re not hurting anybody ... except every single person who freaks out because you’re in love with one another.”

He took a lot of flack for the comment ... but when we asked if he thought it would affect his career, Nick replied, "I make movies man. I'm not a politician. If people want to listen to me for theology, that's their problem. I'm about tolerance."
