Tween star Willow Smith was ambushed on stage this past weekend by none other than her tour mate Justin Bieber. Check out the video below as Justin and a slew of others prank Willow on stage.

As told by Ryan Seacrest: “In the video, Scooter and Ryan are seen putting on Willow’s signature neon braids and make-up, pretending to be two of her backup dancers. The two crash the stage, catching Willow off guard while she performed her track “Whip My Hair.” They’re quickly joined by Willow’s brother Jaden Smith and Justin himself who wields a cowbell, reminiscent of Will Ferrell‘s iconic “Saturday Night Live” sketch.”
