No, she hasn't. You could easily answer these questions yourself with a Google search, you know.
If you do a google image search you'll find that most pictures of her "nude" are just other nude women with her head poorly photoshopped onto their bodies. I did see one on there that may have been her, but there's no way to know for sure. Some people are really good with photoshop.
She has been nude its on google images the frst page.
She was nude when she was born
