Though it can hardly matter for its success, the plot of the hush-hush High School Musical 3 (hitting theaters in October) has been blabbed by leading lady Vanessa Hudgens. "It's their senior year," she tells Us, "so there's going to be graduation - and prom!" Adds director Kenny Ortega: "All of the original cast will be back. [But] I have a feeling this will be the end [for the current stars]. This franchise may move to another generation!" Oh lord - not HSM4 starring those creepy Sprouse twins! - Ben Katner
