Even Goofy isn't immune to Justin Bieber's swagger. Over the weekend, the singing superstar joined Christina Aguilera, Jennifer Hudson, Cee Lo Green and Scotty McCreery to tape performances for the upcoming Disney Parks Christmas Day Parade to air on ABC. (Check local listings.) Bieber sang a medley of songs (check out those moves below!) from the Cinderella Castle stage before posing with Goofy in a Santa outfit. "Once I busked in the streets hoping to make money to maybe come to Disney World ... now I performed here. NEVER SAY NEVER. DREAM BIG!" Bieber tweeted.
