Kate Upton is the new 2012 Sports Illustrated Swimsuit covergirl, an honor that was unveiled last night on The Late Show With David Letterman. The 19-year-old model, who was featured inside last year’s issue, became an Internet sensation last spring when a YouTube video of her dancing in her seat at a Los Angeles basketball game went viral. Watch her and nine other models read last night’s Top 10 List, and then catch her cutting loose doing the Dougie.
