Who wouldn't want to see Kate Upton put something meaty in her mouth? The 19-year-old hottie was an obvious choice when she was recruited to help boost sales of Carl's Jr and Hardees patty melts.

Based on these pictures, we have reason to believe that these burgers are finger-licking good.  By the same token, we won't be surprised if this ad campaign caused thousands to break their New Year's diet and subsequently jump back into the fast food cycle of unhealthy goodness. Cheers to that.
