Some of the High School Musical stars were out at Radio 1 in London doing promotional work for the new High School Musical 3 "Senior Year" movie. Zac seems to only sign one or two autographs and Corbin seems to sign alot of autographs. Vanessa Hudgens can be seen at the beginning of the video arriving. Vanessa's publicist seems to stop her from signing. Tomorrow is the Los Angeles premiere of High School Musical 3. If your gonna be there and wanna share some photo's send them my way. Video was shot by Mr.Paparazzi.
