Rosie Huntington-Whiteley for Victoria's Secret

This week, Victoria's Secret is launching what it expects to be its biggest bra in the company's history -- the Incredible by Victoria's Secret, a new seamless wonder that features memory fit and comes in three shapes: push-up, demi and racer back. And one of the proud models of the Incredible is Rosie Huntington-Whiteley, who recently made headlines by replacing Megan Fox in 'Transformers 3.'

StyleList reports that Huntington-Whiteley will join models Erin Heatherton, Chanel Iman and Candice Swanepoel to wear the Incredible in both print and television campaigns.

Our pals at StyleList caught up Huntington-Whiteley, who is also the face of Burberry and Thomas Wylde. She was talking bras, not explosions and robots.

StyleList: What makes the Incredible by Victoria's Secret different from other bras?
Rosie Huntington-Whiteley: It's the most comfortable bra I've ever worn. It smooths and shapes without pinching your back.

SL: There are three styles. Which is your favorite?
RHW: The demi. It's perfect for everyday wear under a T-shirt.

SL: You appear in your bra and panties in the new ad. What was your exercise and diet routine before the shoot?
RHW: I eat healthy organic food and work out with my trainer Jason Walsh in LA whenever I can.
