Lady Gaga still hasn't recovered from her naked encounter with legendary crooner Tony Bennett, revealing her decision to pose nude for him as he sketched her was one of her most "nerve-wracking" moments.
The "Bad Romance" singer was persuaded to disrobe for Bennett, an acclaimed artist, by photographer Annie Leibovitz for a Vanity Fair photoshoot with the pair who teamed up to record a duet.
And she admits it was a huge moment in her career - because the "I Left My Heart in San Francisco" singer is such a legend to her.
As part of her Thanksgiving Day TV special, "A Very Gaga Thanksgiving," the pop superstar recalled, "True to form, as me giving my all to my work (sic), I walked in and I said, 'Well, Tony, here we are...' and he started laughing and I dropped my robe and I got into my position. It was very, very nerve-wracking.
"I felt shy; it's Tony Bennett. Why am I naked...? The first thing that Tony said to me when I saw him (afterwards) was, 'Wait 'til you see this sketch I did. It's amazing. You look beautiful.'"
The sketch and the Leibovitz photo session appears in the January issue of Vanity Fair.
