Eating a hamburger in a commercial
isn't as easy as it looks!

Carl's Jr. CEO Andy Puzder spoke to the Associated Press about why Sports Illustrated model Kate Upton made the fast food chain's "classic" burger "a lot hotter" but reality star Kim Kardashian did not.

Puzder explained that the Keeping Up With the Kardashians star ended up filming a spot for a salad instead of a hamburger because "she wasn't good at eating the burger."

He also admitted, "If we had not been promoting a salad, we probably never would've done an ad with Kim."

A representative for Kardashian disputed the account, however, and said a salad ad was chosen because she had a fitness DVD and wanted to eat something that tied in more with her brand.

In order to model with the burger, Puzder wants you to really love it. "We don't want somebody that's going to go out there and say, 'Well, I don't eat burgers,'" he said.
