The first official trailer for "High School Musical 3: Senior Year" is now online at Disney.com -- and East High's power couple could be calling it quits. Zac Efron and Vanessa Hudgens' characters talk about parting ways, with Gabriella telling Troy, "I'm a lot better at saying goodbye than you." He responds, "Are you saying goodbye?" The film follows those two and the rest of the Wildcats through their senior year as they
prepare for life after graduation.

The trailer features everything you would expect from "High School Musical," including flashy musical numbers, basketball court dance sequences, and a romantic duet between Gabriella and Troy. The movie will feature 10 new original songs. It's due out October 24th.
