Before taping Letterman on Tuesday afternoon, Sports Ilustrated Swimsuit cover girl Brooklyn Decker tweeted "Oh my Gosh, oh my gosh, I'm at letterman.. Oh my gosh.. I'm shaking. Seriously... This isn't real."
Once there, Brooklyn seemed cool as a cucumber. When Dave asked her how she met her husband Andy Roddick she said "It's a very chivalrous story actually. He got his agent to call my agent," she explained to laughs. "I said this guy, he's a catch, and his chivalry...he wooed me. I said this is the man I'm gonna marry and a year later we're married."
She told Dave why she doesn't play tennis with her husband: "I'm pretty competitive, and if it's something I can't beat him at, I don't do it. Which is why I model."
