Lady Gaga announced that her second fragrance will launch this fall. Eau de Gaga is "for the adventurous woman and the man who loves her," according to its ad, which features a man sniffing the pop star's rear end.
Gaga didn't specifically say that Eau de Gaga will smell like her asshole (or any asshole, for that matter) but the ad she posted for the fragrance on Facebook is certainly suggestive of butt stuff. "Adventurous woman" is just another way of saying, "She'll try anything!" the implication of which is almost always anal play.
Anyway, her last fragrance, Fame, was supposed to smell like the "molecular structure of blood and semen," so you never know with her.
