Is Katy Perry Dating Riff Raff? [VIDEO]

Ladies always go for the bad boys after a major break up! Is this true for Katy Perry? Is she dating Riff Raff? He says they are, and TMZ has the proof!

She just broke it off with John Mayer! So, what happens when you mix John Mayer with...

her Ex Russell Brand?

you get Riff Raff?!?! LOL!!

Honestly though, is it that far fetched that she could be dating Riff Raff?

He did take her out for sushi and they went bowling. Sounds legit! LOL!!
