Must-Watch Vid: Matty B Does Katy P!

By  | 

Our fave pint-sized rapper has gone and done it again! Matty B has already rap-ified some of our fave songs, such as Bieber‘s “Pray” and Rihanna‘s “What’s My Name?” so, duh, Katy Perry would be next! Clearly we’re not Matty B’s only fans; Katy’s a fan too! She tweeted “so.. I met this amazing 7 year old kid, MATTY B & he told me he was gonna do a #FIREWORK remix & he did! It’s amazing!”

Amazing is right! Watch Matty B’s “Firework” — and his super cute encounter with Katy Perry!
