Where were the ladies?

John Mayer and Cody Simpson were just a couple of the hot dudes that decided to party at The Nice Guy in Hollywood last night, and for some reason they weren't accompanied by the usual bevy of women! The "Heartbreak Warfare" singer and Katy Perry are rumored to be together despite multiple breakup reports, and the Aussie crooner is said to be romancing Miley Cyrus, but they were nowhere in sight.

In an odd twist of events, it seems Jen Aniston's womanizing ex was enjoying a night on the town with Bob Saget! Who knew they were friends?!
