Aside from a recent cameo on "The Simpsons," the global brand that is Lady Gaga has been relatively quiet in the U.S. in the first half of 2012 as she brought her Born This Way Ball to little monsters in distant lands. The silence won't last long, however; in September, she'll be releasing the title of her third full-length album, which is already in the can.—Jeff Royer
