Even if you haven’t made a pit-stop at Carl’s Jr. in a while, you certainly remember their TV commercials—risqué ads featuring nearly-naked super models eye fu*king you while devouring big, juicy burgers. The fast-food chain more or less invented the genre and bolstered its reputation over the years by attracting up-and-coming talent.

But that’s not to say all of the superstars ‘performed’ at a high level, according to one report.

“We get a lot of actresses, whose names I won’t tell you, who contact us, who we don’t end up using in the ad because they’re not right for the brand,” said Carl’s Jr. CEO Andy Puzder in an interview with AP.

“You really need to be able to eat the burger like you’re loving it. You really have to go at it. You really have to attack it.”

While Puzder talked about kickstarting the careers of Kate Upton and Padma Lakshmi, he also shed light on Kim’s #burgerstruggles.

“We used Kim Kardashian in an ad. But Kim really couldn’t eat the burgers. Luckily, we had a salad we were promoting, so we used Kim in the salad ad. But if we had not been promoting a salad, we probably never would’ve done an ad with Kim, because she wasn’t good at eating the burger.

The CEO made additional comments about her being “tiny” and “too little,” which makes us think that the guy has never seen Kobayashi go to work.

The article notes that Kim’s representatives refute the story, stating that it aligned with her fitness/lifestyle brand. But the bigger issue remains: When it comes to burgers, is Kim’s heart truly in it?
