This past Thursday, Lady Gaga hosted her fragrance launch at New York’s Solomon R. Guggenheim Museum. Gaga’s first scent is called Fame and of course she had to make quite the scene to launch it. Gaga showed up tot he affair in a floral, hooded robe before revealing a lacy get-up that revealed her thong and ASSets. But it wasn’t Gaga’s outfit or perfume that have people buzzing, it’s the fact that Gaga had a tattoo artist on hand to tat her up right there at the party! The singer got a small tattoo in the lower back of her head near her neck line. See the tat below.
