Before he was ever cast in the role of sneaky new villian Sebastian, Grant Gustin tried out for a tap dancing role in Glee's "Singin' in the Rain" number. On February 2, the cute actor shared a performance video he submitted to try and get the role. "The tap video I talk about submitting for my first glee audition? This is it," he wrote. Grant [on left] has got some serious moves, don't you think? We hope Sebastian gets to show off those skills sometime in the future!
