I'm guessing that John Mayer is a boob man, because ever since the two have started dating, Jessica has been showing off her plumpers. This time it was kind of occasion appropriate. Jessica hosted the second anniversary of the Pussycat Lounge at Caesars Palace. I wonder if Asia finally had a chance to perform.

Many more photos of Jessica's boobs (and Eva and Mario having some fun) from the event are after the jump.
