Supermodel Tyra Banks, fed up with the rumors about her fake breasts, attested during her show that she didn't had plastic surgery to reshape them.

Banks, 32, tired of rumors her that her boobs are enhanced, invited a plastic surgeon into her show, to prove her breasts aren't done. She removed her bra under her shirt and told the surgeon to check them and to testify if they are real or not.

The doctor confirmed her breasts are natural, saying their look is the result of using push-up bras.

Tyra says, "It's very frustrating for me to have to live my career with people thinking that, so I'm doing a test on national television with a top plastic surgeon that is gonna show everybody the truth, whether I have 'em or not. You'll see."

The revealing episode will air in America tomorrow (20 September 05).

Banks, born December 4, 1973, began her modeling career at the age of 17 with the Elite agency after flirting with attending college at Loyola Marymount.

She was quickly discovered in Los Angeles, and offered a healthy contract with cosmetics company Cover Girl -- becoming only the third African-American woman in the world to secure such an opportunity.

Her modeling credits include CoverGirl, Swatch, Pepsi, Nike, Tommy Hilfiger, Ralph Lauren, and Dolce & Gabbana, among many others.

She worked with Ralph Lauren and various magazine covers (over 20 to be exact), including, Gentlemen's Quarterly, Sports Illustrated's swimsuit issue, the Victoria's Secret catalog and most notably GQ.

She debuted in the movie business as Omar Epps' love interest in John Singleton's racially charged drama "Higher Learning" (1995) and snagging a stint opposite Will Smith on TV's "The Fresh Prince of Bel-Air". She also played in "Larceny" (2004), "Halloween: Resurrection" (2002), "Coyote Ugly" (2000) and "Love and Basketball" (2000).

In music, Banks has appeared in Michael Jackson's "Black or White" video when Glen Chin morphs into her, and with fellow supermodel Linda Evangelista in George Michael's "Too Funky" video. In 2005, she also recorded her first single, "Shake Ya' Body", featuring basketball star Kobe Bryant.
