After taking off from Comme Ca, Lindsay and her friends headed over to Hyde. That was the last we saw of her for a few hours - until she emerged from the club with this mysterious man hot on her heels!

Anyone want to try to put a name to his face? After all, if he's making Lindsay smile, he sounds like a guy we oughtta know!
