Brooklyn Decker has made the cover of the Sports Illustrated swimsuit issue.

The 22-year-old model and wife of tennis star Andy Roddick was revealed as the 2010 cover girl on Monday's Late Show with David Letterman when a sheet was removed to unveil a billboard version of the cover in Times Square.

Posing in yellow bikini bottoms with her arms crossed over her chest and a bikini top hanging over her shoulder, Decker, who's scheduled to appear on Letterman's show Tuesday, is touted on the magazine cover as "a perfect '10" who "sizzles in the Maldives."
