Move over Bar Refaeli, there's a new bikini babe fronting the Sports Illustrated Swimsuit Edition.

Brooklyn Decker is the magazine's 2010 cover girl.

The identity of the Sports Illustrated Swimsuit Edition's top model was revealed on the "Late Show with David Letterman" when it was officially announced that Andy Roddick's better half will be passed the bikini, er baton, from 2009 swim star Refaeli.

Aside from cheering on her tennis star hubby courtside, Decker has been jet-setting about to be photographed for the highly anticipated issue. We got a behind-the-scenes peek at one such location shoot from these twitpics posted last August.

Now, there's an image, tweeted by an SI editor, of the Ohio blonde looking well-equipped to take on the sexy status (see above).

As for Roddick, he played the supportive man all the way:

"So happy/proud of my wife... the new cover for sports illustrated swimsuit issue!!!! unreal... so excited!!!!!!!!!!," the tennis player tweeted late last night.

Brooklyn will be on hand tomorrow (Feb. 9) at 3 pm ET to answer questions about her Sports Illustrated Swimsuit Edition gig, -- which will be broadcast via UStream.tv -- and will make a follow-up appearance on Letterman when the issue hits newsstands on Feb. 10.

If Bar Refaeli's career since landing last year's cover is any indication, Brooklyn Decker's career is about to take off. Big time.

Along with a reprise in the 2010 SI Swimsuit issue, Bar landed Rampage's campaign two seasons in a row.
