Katy Perry covers Rebecca Black

Pop princess Katy Perry has been known to perform a few cover versions on her current California Dreams tour, but she surprised her Australian audience with something they wouldn't have predicted. 

She appeared in Melbourne on April 28 and treated her fans to a rendition of Rebecca Black's 'Friday'. The songstress put an acoustic twist on the track, which went viral a few months ago and is now one of the most-talked about and most viewed YouTube videos ever, and got everyone involved.
