The Lindsay Lohan rumor mill is churning again this week. This time, the claim is that she is seeing a male model she just finished working with on a photo shoot.

It's being said that she was spotted canoodling with him during a photo shoot at Hollywood's Chateau Marmont hotel on Wednesday. Sources on the set claim the pair couldn't keep their hands off each other during the shoot, running to her nearby hotel room as soon as the photographer said he was finished.

Lindsay and Petey finally emerged from the hotel at 1.30am and drove to nearby Wonderland club, where they spent just under two hours kissing and cuddling in a corner.

Lindsay left the club alone and then later posted a photo of Petey on her Twitter account, with a message about how much she enjoyed working with him.

Lindsay took to her Twitter account again yesterday to then shoot down the rumors of the "coupling".

Just because I hang out w/a boy, that doesn't mean he is my boyfriend. Can't we have friends? Grrrrr! :) have a lovely day everyone

What do you think? Is she trying to keep things on the down low? Or truly just another case of the media getting carried away? She's single, so it shouldn't be a huge deal, right?
