The words “fierce” and “fabulous” are so passé. The new F word for The Tyra Banks Show’s third season is “fearless.”

And to celebrate this theme, Tyra Banks taped a provocative promotional spot on August 5 in which she bravely walked down the streets of New York — without her clothes on!

“The campaign’s message will encourage women to be fearless in their daily lives,” says Tyra.

It’s not the first time Tyra has undressed for her show: Tyra hosted a panty party in 2006 where she and all of her audience members were in their lingerie, and she even strutted her stuff in a bathing suit this year.

So what’s behind this shocking stunt? “Tyra is all about women loving their bodies, in their clothes or not,” explains an insider. “Plus, it’s a new season for the show, which just moved to New York, and she wants it to be more fun.” [via]
