Tyra Banks was on 'Piers Morgan Tonight' (weekdays, 9PM ET on CNN) and the talk -- about skinny models and men being brainwashed to think that's what thy want when, biologically, they want to feel softness next to them -- turned to breast augmentation.

Banks told Morgan about her early days as a model, when magazine covers showed off her assets. People thought she had fake breasts, so to prove that they're real, she once exposed them to the studio audience on her talk show, before having a doctor run a sonogram over them so they could be declared implant-free.
