Lindsay Lohan allegedly hooked up with a male model named Petey Wright last night. Yesterday, she and Petey were photographed (The Sun has photos here) leaving the Chateau Marmont after maybe spending the night together. However, Lindsay denies that they hooked up. Much in the same way she denied the Balthazar Getty hookup, she went to Twitter (“Just because I hang out w/a boy, that doesn’t mean he is my boyfriend. Can’t we have friends? Grrrrr!”) and Gossip Cop to tell her side of the story. Gossip Cop reports: “Lohan told Gossip Cop, ‘My photo shoots consist of work and only work.’ More importantly, when we asked if it was true that she was hooking up with the model, she simply responded, ‘NOT.’” Who’s buying it? Not me. Here’s The Sun’s report:

LINDSAY LOHAN has gone back to boys, and here’s the proof.

The Mean Girls actress was snapped leaving the Chateau Marmont hotel in Hollywood with a male model called PETEY WRIGHT, after the pair spent the night together.

The couple had been seen kissing at a nearby nightclub the night before.

The sexually fickle star, who split with DJ SAM RONSON earlier this year, met Petey at a photoshoot at the hotel on Wednesday and, according to onlookers, it was instant attraction.

“Lindsay was all over Petey during the sexy photo shoot, and it continued when the shoot ended,” a source told X17. “They headed into a room at the Chateau for two hours and Lindsay couldn’t keep her hands off of him – and vice versa.”

The lovebirds then moved on to Wonderland nightclub, where a staff member revealed they spent two hours kissing in the corner.

“Oh my god! I was at Wonderland club tonight and Lindsay was there with some hot model guy named Petey,” said the insider.

“She posted a picture of him on her Twitter! She had her hand on his leg the whole time between kisses, and they stayed for two hours. I can’t believe it!”

Eh. I think Lindsay did hook up with this guy, but it was probably in an effort to make Samantha Ronson jealous… because I could totally see Lindsay’s mind working that way, couldn’t you?

In other Lindsay Lohan news (we didn’t do anything about her yesterday, so this is your “48 Hours of Lohan” post), her bodyguard was arrested yesterday under mysterious circumstances. We still don’t know why he was picked up and handcuffed by the police, but my guess is that it involved drugs. Just a guess. Also, Michael Lohan is still a son of a bitch. Some sources have him trying to hook Lindsay up with his “good friend” Jon Gosselin. Michael is also threatening to release tapes of Dina Lohan “admitting” that Lindsay has a drug problem and is at “death’s door”. Whatever.
