There's a perfectly good reason why this is happening, but we'd prefer to forget about it and wax insane about the naked rituals of the ruling celebrity elite. Apparently, getting a nude sketch done by Tony Bennett keeps you eternally young!

Basically, photographer Annie Leibovitz suggested that Gaga let Tony sketch her naked. Gaga said it was an anxious affair: "I walked in and 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 a little bit ... I felt shy. It's Tony Bennett, why am I naked?'" You can see Tony's work in the picture above. It's not bad! The smooth old crooner can swing a pencil (er, charcoal?) with the best of them. It's a shame Mr. Bennett doesn't make amateur adult movies in his spare time, otherwise this Vanity Fair article would've taken a way different turn.
