2012 Sports Illustrated Swimsuit Issue cover girl Kate Upton adds some extra heat to the latest Carl's Jr./Hardees commercial by rolling around all sexy-like with their new southwest patty melt.

Never before has a patty melt looked as good as it does in the mouth of uber hot model Kate Upton. She's been haunting our dreams ever since the first time we laid eyes on her and now we can't look at a cheeseburger without getting an erection. We're still trying to figure out how this commercial didn't win an Oscar the other night.
