LOS ANGELES (Reuters) - Supermodel Tyra Banks underwent a sonogram on her own television show to quell rumors that she had breast implants.

Banks, 31, told the audience for her syndicated talk show on last Tuesday that she was tired of rumors that her breasts were fake. "It's something that's followed me forever and today I'm going to finally admit once and for all the truth about my breasts," the Victoria's Secret model said as she removed her push-up bra from underneath a T-shirt.

She took a break and returned wearing a bathrobe and accompanied by plastic surgeon Garth Fischer. He and an assistant performed a sonogram in front of the audience that was broadcast with certain part of Banks' anatomy blacked out. Fischer said, "I've performed approximately 8,000 breast implant surgeries, I've examined you, I've reviewed your sonogram ... and Tyra Banks has natural breasts."
