Lady Gaga, known for her unique fashion sense, shocked guests at the launch party of her perfume Fame here when she sat down to get herself inked live in front of the crowd.
Gaga arrived at the venue in a convertible car, before laying down inside a giant replica fragrance bottle.
She later emerged from the bottle wearing nothing but lingerie and then sat down to have a tattoo inked on the back of her head.
Gaga recently shaved off the hair at the back of her head in support of her photographer friend Terry Richardson, whose mother died Sep 10.
She got the space filled with a tattoo of a winged cherub.
