The 41-year-old model said the politician was "so relaxed and so cool", reported Ace Showbiz.
"We talked about cellulite and she was like: 'Yeah, I've got cellulite, and I look in the mirror, and I don't have any clothes on, and I don't like everything I see'. It was that kind of conversation," Banks said.
She had the privilege of having Clinton on her talk show back in 2008. The supermodel admired her personally since.
"She was just so free-flowing... The standard media take on her is that she is cold and that she's calculating and that she doesn't loosen up. Oh my God, she was so relaxed and so cool!" Banks gushed.
