Katy Perry makes John Mayer “her mission” — gonna be a quick mission!

John Mayer seems to be ‘that guy’ — the douchebag who somehow convinces the hottest girls to hook up with him. The latest of his victims is said to be Katy Perry… only she is volunteering!

Katy has apparently had a thing for John Mayer since back in 2009 when they hit it off at NYC’s Goldbar. A source said, “she made it her mission to hook up with him.” They wound up leaving separately though and the very next day she met Russell Brand.

Now that she’s officially single again, it sounds like she’s back on her mission of making John her man, well, for a night anyway. Smart! He’s doesn’t seem good for much longer than that. 

The rumors really started to heat up after Katy and John Mayer spent last Friday night together at West Hollywood’s Soho House. “They were affectionate, holding hands and cuddling!” says a witness. The duo had an encore the next night, when the Montana-based crooner, 34, shared pizza with Perry, 27, at her house. Pizza! This is getting serious! But, wait, what about what’s his name? Umm.. Musician Robert Ackroyd…? Katy has also been dating him.

Is this JUST the beginning of new romances for Katy? 

Who is worse Russell Brand or John Mayer?
