Hudgens will make her SYTYCD debut in part one of the Los Angeles auditions, which can be seen during the season premiere on June 12.
"I am so excited for Vanessa to join Mary and me on the judging panel for the 14th season of So You Think You Can Dance," Lythgoe, who also executive produces the series, said in a statement. "There was instant chemistry in the audition rounds, and I know the SYTYCD fans will love her as much as we do. Vanessa is an accomplished artist and brings her own brand of enthusiasm and energy to our panel."
Hudgens began her work in musical theater at a young age with shows like The Wizard of Oz and Cinderella, but is perhaps best known for starring in Disney Channel's High School Musical opposite Zac Efron.
