Dancing With The Stars competitors Scott Hoying and Rylee Arnold busted a move to High School Musical's "Bop to the Top" this week - and now Ashley Tisdale is weighing in. Tisdale, who famously performed the song as her character Sharpay in the Disney movie, took to TikTok on Friday, October 10, to share her take on the reality TV show recreation. The social media clip showed the singer sitting on a bed as she watched the performance by Hoying, 34, and Arnold, 20, on her phone while being filmed by an unknown person.
