Typically reserved for Paris Hilton, Audrina Patridge, and rookie Sports Illustrated swimsuit issue models (see a younger Kate Upton eat a Southwest Patty Melt!), Carl's Jr. and Hardee's next TV spot features Heidi Klum, who promotes their Jim Beam Bourbon Burger. "What I love about the commercials is that they're always super sexy, but they also have a lot of humor to them," Klum tells the camera in this behind-the-scenes video. "My favorite part is always when this beautiful girl bites into this gigantic burger and it has that sound effect of [chomping noise]." Her ad is Graduate-themed — "Basically, I am playing Mrs. Robinson, and I'm seducing this cute, little boy with my burger," Klum explains. As for the casting decision, "[Heidi]'s a little bit higher level and I think this product is for mature people ... for mature tastebuds only," Justin Hooper, one of the advertisement's creative directors, remarks. This one's going right over Carl's Jr. customers' heads.
