Kate Upton strips for Carl's Jr. ad

London, Mar 1 (ANI): Kate Upton is seen stripping down in the new Carl's Jr. and Hardee's commercial for the fast food giant's Southwest Patty Melt, which surfaced on Thursday.

The Sports Illustrated model, who has been linked to NFL star Mark Sanchez, is seen writhing around with a big juicy burger in hand as she promotes the chain's seasonal addition.

The 19-year-old is seen arriving at a drive-in movie before swiftly tucking into her bag of takeout food.

A fairly demure-looking Upton whips off her headband after taking one huge bite into the burger, unleashing her long blonde tresses.

The model then begins sweating as she devours jalapenos peppers individually, leading to her untying her pink bolero and readjusting herself in a polka dot dress.

The television advert is a little racy as she elevates her legs to reveal part of her derriere above her black stockings.

Throwing her head back in enjoyment, Kate begins to receive attention from a male admirer in the adjacent vehicle although his girlfriend clearly isn't impressed.

The star - who has openly spoken about her love of eating in the past - proceeds to lay back on her car seat, kicking her toned legs up in the air.

She then climbs over to the front where she reaches for a refreshing beverage to cool her down, leaving her backside for all to see.

Upton is the perfect ambassador for the calorific burger. Her friends staged an intervention last year when they thought the model had put on too much weight.

The 2012 Sports Illustrated swimsuit issue cover girl has said that she has a healthy appetite and attitude towards food making her the perfect choice for the campaign.

The swimwear model seems like she's in heaven as she indulges in the meaty delight which spices up a classic by combining 'premium quality ingredients including spicy Santa Fe sauce, grilled onions, Pepperjack cheese and jalape¤os to create a unique flavoured burger on a toasted sour-dough bun.'

The commercial was filmed on a hilltop overlooking downtown LA and apparently she is the best star the makers have had so far.

"Kate's probably the hottest girl we've ever worked with," the Daily Mail quoted Justin Hooper creative director as saying.

In another image Upton is seen straddling the Carl's Jr. takeaway bag as she looks seductively into the camera with her ample assets on full display. (ANI)
