Auction of Lady Gaga’s Nude Sketch From Dec. 12–19

Lady Gaga posed nude for singer Tony Bennett so he could sketch her and now one lucky fan might be able to nab the work of art.

The sketch of Lady Gaga is part of an auction of artwork from Vanity Fair that includes items singed by Gaga as well as famed celebrity photographer Annie Leibovitz.

One of Bennett's nude pictures of Lady Gaga is also set to appear in the January 2012 issue of Vanity Fair magazine, at the suggestion of famed celebrity photographer Leibovitz.
