Who is singing for sterling knight in starstuck?

Answer 1

no one he is

Actually, Sterling just sings "Starstruck" main vocals. Drew Ryan Scott sang "Hero", "What You Mean To Me", "Shades", etc. He also sang the backgrounds for Sterling in "Starstruck".This was because Sterling was called in too late in filming production (he replaced Cody Linley for an unknown reason), so Sterling didn't have enough time to memorize the songs and his scripts, not to mention record the songs as well. So, Drew was hired as his voice double. He is also recognized in the credits.

Answer 2

Sterling Knight's singing voice in the movie "StarStruck" was actually provided by Drew Ryan Scott. He was brought in to record the vocals for Knight's character in the film.
