Zac Efron left LA's El Rey Theater last night after catching a live performance by Plan B with a group of his friends. He had an evening of music despite skipping this year's Coachella, which he hit up in 2010 with then-girlfriend Vanessa Hudgens. Vanessa was among the stars at the desert festival last weekend, and her attendance made headlines. She was snapped eating what appeared to be an illegal white substance, but Vanessa's rep claims it was melted white chocolate. Vanessa's spending time with her Journey 2: The Mysterious Island costar and rumored new flame, Josh Hutcherson. Zac hasn't moved on quite as quickly, though the sexy star isn't hurting for female company and he was reportedly spotted with Victoria's Secret model Candice Swanepoel at yesterday's concert.
