HIGH SCHOOL MUSICAL sweetheart Ashley Tisdale has become the new face and voice of deodorant Degree Girl. The singer/actress has recorded a batch of new songs for the campaign. She says, "You can download them on DegreeGirl.com." The campaign also features a write-in competition where Tisdale fans can tell all about their sweatiest moment; the best entry will win a trip to Los Angeles to meet the star, who has no qualms about her new links to a deodorant. She adds, "People sweat. No one's perfect."
