Ashton Kutcher brought his charm and a great blue shirt to The Late Show yesterday, where he cracked up Letterman with stories about growing up in Iowa, being a frat boy, Cameron Diaz's "superhero butt," and Demi's anti-aging leech treatment (don't worry, it confuses him too). Ashton has been looking great and turning on the handsome charisma out promoting What Happens in Vegas. He may have just turned 30, but he seems to be getting better with age. Between the cast's adorable chemistry and the promising trailer, I can't wait to see what exactly happens in Vegas.
