Looks like Rebecca Black's infectious Internet hit is soooo addictive, that even Katy Perry got hooked. On Friday April 29th during a concert in Melbourne Australia, Katy covered Black's YouTube song. Peep the action in the video below!
What do you guys think of Katy's cover? Does it improve on the original version which everyone hated so much that Rebecca got death wishes sent among thousands of other hate-mail messages?
