American actress and singer Vanessa Hudgens has really shocked her boy friend Zac Efron by expressing her thought that she wants to have an open relationship. Hudgens, 20, was apparently furious after Efron said he didn't want to get married until he is 40 and this is the reason she is seeing other people to make him jealous. That's ridiculous!! "When Vanessa heard about Zac's plan to stay single for the next couple of decades she was shocked and shattered," a source told the National Enquirer magazine. "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." What will be the reaction of Zac after knowing this weird thought of Vanessa? Will this relation last long? Let's wait and watch for the answer.
