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.
Speaking about the experience on CBS TV special 'A Very Gaga Thanksgiving' which aired last night (24.11.11), she said: "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?' "
The pictures that Tony sketched of Gaga, 25, will be published in Vanity Fair magazine next year.
At the beginning of the holiday show, the two singers performed 'The Lady Is A Tramp' – the track they recorded together for Tony's album 'Duets II' – together, and later Gaga admitted she has a special connection with Tony.
She gushed: "Oh Tony he’s so handsome. I feel terrible whenever his wife is around because he is so charming and such a gentleman."

And it appears the feeling is mutual with the 'I Left My Heart in San Francisco' singer saying: "She is the most beautiful person I ever met but there is something very special about her."
In an interview with Katie Couric for the programme, Gaga revealed she hates to talk about her romantic life and when she eventually gets married she insists won't reveal any details of her nuptials.
The pop superstar said: "My love life is the only thing I don’t talk about. The day I get married, no matter how many helicopters are flying over that chapel, they are not getting one picture.
"I don’t know how artists do it. Talk about their lives and marriages and divorces and boyfriends. It’s sacred in a different way and I would rather reveal it in a poetic way."
Gaga also performed several hits for her TV special including 'Edge of Glory', 'Born This Way', and 'Hair'.
