Sharon Osbourne isn't a fan of Ashton Kutcher. During a recent E! News segment titled "Stirring the Pot," Sharon identified Kutcher as the rudest celebrity she's ever met — although she couldn't actually remember his name at first. "The guy that's married to an actress and he used to do That '70s Show," Osbourne said when asked to reveal the rudest famous person she'd ever encountered. After being reminded of Kutcher's name, Sharon confirmed, "Yes! Oh, rude, rude, rude, rude, rude little boy." She didn't offer any details, but added, "Rude, rude, yes. Dastardly little thing."
