Tyra Banks Is a 350-Pound Woman for a Day

LOS ANGELES – Tyra Banks (search) has gone undercover as a 350-pound woman.

Banks wore the fat suit to experience what it's like to be obese.

"It seemed like the last form of open discrimination that's OK, and I decided to put on a 350-pound suit myself and live that life for a day and see what happens," the 31-year-old former supermodel told AP Radio in a recent interview. "And it was one of the most heartbreaking days of my life."

Banks said she was shocked at the reaction.

"I started walking down the street and within 10 seconds, a trio of people looked at me, snickered, looked me right in my eye and started pointing and laughing in my face," the talk-show host said. "And I had no idea it was that blatant."

The segment will air Monday on "The Tyra Banks Show (search)."

Banks, who had a sonogram on her show in September to prove that her breasts are real, is also planning a Nov. 18 segment on pursuing "a beautiful booty."

She will reveal her own "dimpled butt" and receive endermologie (search) treatment on the set.
