Is this the sexiest fast food advert ever? Semi-naked Heidi Klum seduces toy-boy with juicy burger in new Carl's Jr commercial

American burger chain Carl's Jr are known for persuading beautiful models and actresses to advertise their latest inventions.
Audrina Patridge, Padma Lakshmi, Kim Kardashian, Emily Ratajkowski and Kate Upton have all licked their lips lasciviously for the camera before tucking into a calorific meat and bread snack.
The juxtaposition of their toned, slim physiques might jar with the meat juices dripping down their chins but these commercials have proved to be a winning formula for the chain.
And now they've landed their biggest name to date in the form of stunning supermodel Heidi Klum.

Delicious: Heidi Klum scoffs Carl Jr's new Jim Beam Bourbon Burger in the latest and sexiest advert for the American chain

Unsurprisingly, the 39-year-old's commercial for the Jim Beam Bourbon Burger is probably the sexiest installment yet... and perhaps the hottest in the history of fast food commercials. 

In it, the mother-of-four strips down to skimpy negligee and shows off her cleavage as she gets to grip with the southern inspired new addition to the menu.
Klum plays a seductress in a recreation of the famous Mrs Robinson scene from Dustin Hoffman's movie classic The Graduate.

Hungry yet? Heidi tucks into the delicious looking snack with gusto and insists she does eat burgers (and fries) regularly)

Two-pronged attack: Heidi proffers the juicy burger to the young man with her cleavage prominently on display

'Basically, I am Mrs. Robinson and I am seducing this cute little boy... with my burger,' Heidi said in a behind-the-scenes video.

'I shove the burger in his mouth in a sexy way,' she adds.

The commercial's creative director Mick DiMaria explained: @We're basically taking that scene and foodifying it.'
