lady Gaga Sketch To Be Auctioned On ebay (PHOTO)

Ton Bennett”s nude sketch of Lady Gaga, made during an Annie Leibovitz photo shoot for Vanity Fair, is up for auction. Bennett, who is a painter as well as a singer, made the drawing at Leibovitz’s urging.

The sketch is up for sale at eBay Celebrity, with proceeds to benefit the singers’ foundations – Bennett’s Exploring the Arts and Gaga’s Born This Way. The two singers recorded a version of “The Lady Is a Tramp” for Bennett’s recent Duets II album.

On her Thanksgiving TV special, Gaga joked about posing for the picture. “I walked in and said, ‘Well, Tony, here we are,’ and I dropped my robe and I got into position,” she recalled. “I felt shy and thought, ‘It’s Tony Bennett. Why am I naked?”
