Yup - we (and everyone else) called it - and now, Brooklyn Decker, the 22-year-old wife of tennis star  Andy Roddick, is the new Sports Illustrated Swimsuit Edition cover girl.

The big reveal went down last night on David Letterman, which began as a teaser when Letterman pointed to a fake billboard of a naked Scott Brown, but then  a sheet was removed from the real SI billboard in Times Square to unveil Decker in a yellow bikini.

"I still don't know the formula for the cover," Decker said. "It's luck, the perfect suit and perfect storm to get it."

Sports Illustrated encourages a natural look and Decker said that because of this, it was  easier to get a  good photograph. "This celebrates the girls and their personalities. I think it's why they get such beautiful pictures."

To celebrate, the Sports Illustrated swimsuit models will be heading to Vegas for three parties which are planned at Jet Nightclub at The Mirage Hotel & Casino and Vanity Nightclub at the Hard Rock Hotel & Casino. Check out the Sports Illustrated promotional video. Also, tonight CNBC takes an exclusive look inside the billion dollar multimedia Sports Illustrated Swimsuit franchise.  Check out the  exclusive Brooklyn Decker footage.
