The hand-drawn image of the singer was auctioned on eBay to benefit her and Bennett's respective foundations.
Lady GaGa's nude sketch made by Tony Bennett went under the hammer online and fetched $30,000. The charcoal-on-paper artwork was one of the items related to GaGa that were sold on eBay charity auction.
The sketch was done as part of a cover story and layout of Vanity Fair's January issue. Signed as Bennett's real last name "Benedetto", the piece depicts GaGa's pose when she did a photo shoot with famed photographer Annie Leibovitz.
"I walked in and said, 'Well, Tony, here we are,' and I dropped my robe and I got into position," GaGa said in a TV interview. "I felt shy and thought, 'It's Tony Bennett. Why am I naked?" GaGa and Bennett collaborated in a new cover of "The Lady is a Tramp" for his duets album.
Another item put up for auction was an autographed poster of the Vanity Fair cover featuring GaGa and some of the accessories she wore during the shoot. Exploring the Arts, Bennett's organization supporting arts education in public schools, and GaGa's Born This Way Foundation would benefit from the auction.
