Katy Perry may have moved on from her on & off again John Mayer. Word is the singer was seen all over MUSE drummer Dominic Howard after one of his gigs.
Well don’t think John is sitting at home lonely either…
Mayer was also spotted on the town having a good time at a hotel party with actress Allison Williams from “Girls”.
Wonder what this is all about… maybe they’re swingers! What do you think?
