Los Angeles, Sept. 22 (Reuters): Supermodel Tyra Banks underwent a sonogram on her own television show to quell rumours that she had breast implants.

But first she ordered all the men out of the audience, a spokeswoman for her programme said yesterday.

Banks, 31, told the audience for her syndicated talk show on Tuesday that she was tired of rumours 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.

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.

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.”

Banks added, “By no means am I against plastic surgery, by no means am I saying that breast implants are a bad thing, but it’s just not a choice that I made ... it’s something that a lot of people think I have and that is so frustrating to me.”
