The Canadian pop star posted the video on his Twitter page on Monday, complete with a reference to his favorite icon. "NEVER SAY NEVER with me Justin Bieber and my lil bro Jaden Smith," he tweeted. "CHUCK NORRIS APPROVED!!"
In the video, we see the two stars hanging out in the studio, watching The Karate Kid. Justin is laying down his smooth vocals while Jaden is chillin' beside him. Clips from the movie are mixed in with shots of the talented duo, and after about two minutes, Jaden breaks out into a rap that would make his dad, Will Smith, proud.
Check out the full video below for sneak peeks of the action-packed movie. Make sure to watch until the end to see Jaden wrestle Justin to the ground. The Karate Kid opens in theaters nationwide on June 11.
