Pop sensation Lady Gaga says she posed nude for singer Tony Bennett,so that he could draw her. The 'Mary the Night' singer has revealed she posed nude so the 55-year-old crooner could draw pictures of her and the idea was conceived by renowned photographer Annie Leibovitz,reported E! online. I walked in and said,'Well Tony here we are,' and I dropped my robe and I got into position. I felt shy and thought,'It's Tony Bennett,why am I naked? she said. The pictures that Bennett sketched of Gaga,25,will be published next year. The two singers recorded together a track together named 'The Lady Is A Tramp',for Bennett's album 'Duets II' and Gaga also said that she has a special connection with Bennett.
