Zac Efron sported a sexy crew cut as he stepped out of ex-girlfriend Vanessa Hudgens's house in LA this afternoon. It was the second day in a row he was spotted at her place, sparking rumors that the longtime flames may have rekindled their relationship. The two split last month when he was in Louisiana shooting The Lucky One, which is the reason for his sheared hairdo. He was one of the single guys we would have most liked to kiss under the mistletoe over the holiday, and there were stories he was cozying up to costar Taylor Schilling while in the South. Zac and Vanessa are both nominees at tonight's People's Choice Awards, and he's expected on the red carpet, where we'll be streaming live in just a few minutes!
