For the Lady Gaga with everything, a very public tattoo

NEW YORK (AFP) - Lady Gaga marked the launch of her debut perfume Fame by making herself the centerpiece of a surreal black-tie masquerade soiree and getting a tattoo on the back of her head.

Gaga, 26, took over the Guggenheim museum on the final day of New York fashion week for a piece of performance art - or should that be publicity? - that started off with her sleeping in a Plexiglas replica of a Fame bottle.

Hundreds of guests - including Paris Hilton, Lindsay Lohan, Yoko Ono and a host of big-name New York fashion designers and models - had been asked to turn up on Thursday night with full-on head accessories, or at least a party mask.

"In the spirit of Gaga's nostalgic aesthetic, we inspire you to honour her dedication to this fragrance and celebrate your shared passion for fashion," the invitation card said.
