She’s only 19, but High School Musical star Vanessa Hudgens has some sage advice on love and relationships.

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

As for her own love life – she’s dating HSM costar Zac Efron, 20 – it appears she’s taken her own advice.

According to the magazine, the two share an easy and affectionate relationship. Upon seeing the couple together, the magazine interviewer observes, “When [Vanessa] sees Zac, she runs over and they kiss, oblivious to the dozen of us in the room. She rubs his stomach, he puts his arm around her – these gestures say more than any statement she could make.”

Hudgens and Efron, who are currently filming HSM 3 in Utah, have certainly shown they’re not opposed to a little PDA. Prime example: This year’s MTV Movie Awards, where she planted a kiss on him as his name was announced.

But Hudgens – who endured a nude photo scandal last year – cautions teen girls who may be thinking of becoming more intimate with their boyfriends.

“You have to think it through, not just do something spur of the moment,” she says. “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.”
