Vanessa Hudgens is only 19.

But the High School Musical star has spent enough time in the spotlight and in a relationship (with Zac Efron, perhaps you've heard of him?) to offer advice on love and dating.

"If you really love someone, you shouldn't have to work at it," the actress tells Cosmo Girl! for its July/August issue. "You finish each others' sentences and have the same sense of humor."

Give it up for Zanessa!!!

Following the release of Vanessa Hudgens nude pictures last year, the actress also cautions young girls who may be thinking of growing more intimate with their boyfriends.

"You have to think it through, not just do something spur of the moment," she said. "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."
