Is Katy Perry dating John Mayer?
A few weeks after ex-husband Russell Brand stepped out with new girlfriend Isabella Brewster, Katy Perry was snapped Wednesday night leaving Chateau Marmont with the 34-year-old musician.
The photos add fuel to rumors from late last month that the pair were seen "holding hands and cuddling" at West Hollywood hot spot Soho House.
If Perry and Mayer really are dating, he's certainly solidifying his reputation as the rebound boyfriend of choice for Hollywood divorcees. After her 2005 divorce from Nick Lachey, Jessica Simpson wound up in a nine-month relationship with the musician that lasted from August 2006 to May 2007. Then, Jennifer Aniston began an on-again-off-again relationship with the notorious ladies' man in April 2008, a few years after her divorce from Brad Pitt.
