According to a UK website, Rosenberg said that the 55-year-old singer has acknowledged in past interviews that she did pose nude for art classes when she was a model and that she feels that she's never done anything she's ashamed of.
The photos taken by photographer Herman Kulkens in 1977, shows the then 18-year-old University of Michigan student posing fully naked both on her own and with another female model, the New York Daily News reported.
The pop diva was paid just 10-dollars-an hour for the photo shoot, and some of the images were published by adult magazines such as Playboy and Penthouse in the 1980s.
The full set, currently owned by American financier Jeremy Frommer, is set to go under hammer on November 9 at guccionecollection.com.
