Katy Perry -- The Pies Have It

TMZ TV


Does Katy Perry have an obsession with pizza, just because she ordered out for it ... while partying in a Las Vegas nightclub ... where she's supposed to be watching her boyfriend Diplo's concert?

Of course not. It's her pizza onesie and selfies in the bathtub WITH a pizza that put her over the line.
