VHUDGENS090907_019.jpgWow, how long are they gonna be promoting this movie?! The L.A. premiere was back in early July, and now the Hairspray kids are in Australia hawkin' the flick! Zac Efron signed some autographs while Vanessa Hudgens, uh, well...Zac Efron VHudgensCuteorSexy.jpg...couldn't decide if she should act "cute" or "sexy" for the cameras. Still feeling awkward about that nude photograph scandal, Vanessa? It shows!
