Heidi Klum is just the latest sexy star to shill burgers in a commercial for Carl's Jr. and Hardees.

Heidi Klum mother of four children hawks the new Jim Beam Bourbon Burger, in a swimsuit no less, for the "Graduate" themed commercial, which will begin to air nationally on March 25.

"Basically, I am Mrs. Robinson and I am seducing this cute little boy... with my burger," Klum explained in the behind-the-scenes video. "I shove the burger in his mouth in a sexy way."

And if you're wondering if someone as fit as Klum actually eats what she promotes (in this case a 960 calorie burger) -- well, she says she does:

"I do eat a lot of burgers. I do also eat a lot of fries."

We're not sure if we believe her, nor do we really believe that Kate Upton, Paris Hilton and Audrina Patridge regularly scarf down burgers either.
