Who's hungry? Heidi Klum steams up the screen in a new commercial for Carl's Jr. and Hardee's, set to debut later this month, by devouring a hefty burger in front of a bewildered young man.

The supermodel, 39, dons a very revealing, low-cut little black dress in the sexy TV spot, in which she takes on a Mrs. Robinson-inspire role in The Graduate-style commercial.

Her seduction tool of choice? A Jim Beam Bourbon burger that she bites into seductively as she plays up her famous curves.

The mother-of-four isn't one to shy away from an opportunity to flaunt her figure, however.

In January, the Project Runway host climbed on top of Jay Leno's desk to show off her dance moves in a sleeveless black dress with sheer side panels.

"It's easy," she told the talk show host of getting her moves on on the dance floor. "You just get up. You have to make sure you have a good person holding your hand, and then you dance."
