Zac Efron is said to be shocked after girlfriend Vanessa Hudgens asked for an ‘open' relationship, insiders have told the National Enquirer magazine. The actress is said to have asked for the arrangement after reading a recent Efron interview where he said he didn't want to get married until he is 40. "When Vanessa heard about Zac's plan to stay single for the next couple of decades she was shocked and shattered," a source claims. "She'd secretly hoped for an engagement ring within the next year or two! Zac's totally upset - he doesn't want Vanessa dating anyone else. Even though he's not ready to commit himself to settling down at this stage of his young life, the thought of Vanessa in another man's arms drives him crazy."
