Today, the folks at Sports Illustrated have unveiled their Swimsuit Issue cover model as Brooklyn Decker, wife of tennis star Andy Roddick.

The world of the Sports Illustrated swimsuit issue is far more cloak and dagger than you’d ever guess. The issue is kept under wraps until the day before it’s released and even the models don’t know who’s going to be on the cover.

Apparently everyone just shows up at the beach, looks hot for some photos and they get surprised like the rest of us when the magazine hits the stands. In Brooklyn’s case, we’re particularly impressed by the accomplishment, since half of her swimsuit isn’t even on properly. Brooklyn is also going to be at Fashion Week 2010, hopefully modeling off some similar bikinis. You can get a run down of the events and schedule of the event found here.
