Vanessa Hudgens doesn't want to marry Zac Efron.

The 20-year-old actress, who has been dating her 'High School Musical' co-star for around three years, wants to concentrate on her career and isn't ready to settle down.

She added to People magazine: "The fact that kids look up to me is flattering. But at the end of the day, I want to do R-rated films, and I want to do things that are a bit edgier, so maybe some kids can't see some of them. "I just think it's really important to try different things. I think a lot of people get stuck doing the same routine, and I'm just not content with that. I love trying new things and doing new hobbies and just exploring life."

Vanessa plays a girl who ends up in a mental institution after being abused by her stepfather in 'Sucker Punch'.
