Justin Bieber‘s affinity for pranks is no secret, and that proved true Sunday when Bieber was joined by his manager Scooter Braun and swagger coach (among other things) Ryan Good to ambush tour-mate Willow Smith in Manchester, England.

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.

Count on Willow to get her revenge soon though, as she tweeted, “My big brother’s Justin and Jaden pranked me on stage tonight…#payback!!!” Willow is joining Justin for the entire European leg of his tour.

Willow’s second single “21st Century Girl” — which RyanSeacrest.com world premiered last month — is now available for download on iTunes here!
