The 'High School Musical' actress, who has been dating her co-star Zac Efron for over two years, insists her relationship is easy because she and Zac are such a perfect match.

She told Cosmo Girl magazine: "If you really love someone, you shouldn't have to work at it. You finish each others' sentences and have the same sense of humour."

Vanessa - who is currently shooting 'High School Musical 3: Senior Year' with Zac - also warned her female teenage fans to think first before getting intimate with their boyfriends.

She added: "You have to think it through, not just do something spur of the moment. So that after it happens you won't regret it. I think girls can be infatuated with their boyfriends and they have to remember to put themselves first."
