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.” (people.com)
