Hollywood starlet Lindsay Lohan, who has an on-off relationship with DJ Samantha Ronson, has been spotted kissing a male model, sparking rumours that she is dating the guy.

The 23-year-old actress, who shared a lesbian relation with the DJ since 2008, met model Petey Wright during a photo shoot at a hotel in Hollywood on Wednesday, reported Contactmusic.

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 done.

"Lindsay was all over Petey during the sexy photo shoot, and it continued when the shoot ended. They headed into
a room at the Chateau for two hours and Lindsay couldn't keep her hands off of him and vice versa!," said a source.

The Mean Girls star and Wright finally emerged from the hotel at 1.30am and drove to nearby Wonderland club, where they spent their time kissing and cuddling in a corner.

"Oh my god! I was at Wonderland club tonight and Lindsay was there with some hot model guy named Petey," said a hotel staff.

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