Katy Perry & John Mayer — Sooooooo Dating

0812_perry_mayer_videoKaty Perry and John Mayer don”t need to say it … they”re definitely an item. 

The pair have been spotted all over town recently and last night … our photog caught them coming out of a house party in Los Feliz. Not a lot of recording sessions done at house parties in Los Feliz.

The couple() didn”t say a word — and neither has commented publicly on the relationship() — but come on … we know what”s up.

John Mayer does it again.
