The avant-garde pop star reclined in a replica of her "Fame" fragrance bottle at the masquerade black tie event, where the few hundred guests included Yoko Ono, Marc Jacobs, Paris Hilton and Lindsay Lohan - who arrived late.

Inside the bottle, Gaga lounged in a sparkly top, black skirt and red wig, applying make-up and playing on an iPad. She stripped to her lingerie, took off her wig and began receiving a tattoo of the back of her neck.

She arrived on top of a convertible outside of the Solomon R. Guggenheim Museum on New York's Upper East Side, where she posed for pictures and interacted with fans.

Gaga also debuted a short film for the fragrance in collaboration with director Steven Klein.

The Grammy-winning singer released her multiplatinum debut, "The Fame," in 2008. That was followed by the platinum-selling albums "The Fame EP" and last year's "Born This Way."
