Katy Perry has unveiled a video of herself covering Carly Rae Jepsen's 'Call Me Maybe'.
The video, which you can watch below, appears to have been shot while Katy was at the Coachella festival in Los Angeles last weekend.

The video ends with Katy coming close to the camera and saying: "We love you Justin Bieber." The 'Boyfriend' star signed Carly to his record label Schoolboy Records.
