Justin Bieber to Willow Smith: More Cowbell!

by at . Comments

During a tour stop in Manchester, England last week, Willow Smith was greeted by a surprise guest and an unexpected request: more cowbell!

Indeed, Justin Bieber jumped up on stage during a rendition of "Whip My Hair," pounding this unusual instrument and getting into it like Will Ferrell in arguably the greatest Saturday Night Live sketch in history.

Jaden Smith also joined in the fun, which led the following Tweet from Willow: “My big brother’s Justin and Jaden pranked me on stage tonight…#payback!!!” (Willow is opening for Justin on the European leg of his tour.)

Watch the hilarity below.
