Kate Upton makes burger sexy as she strips down in racy Carl's Jr. commercial

Kate Upton’s highly-anticipated Carl’s Jr. and Hardee’s commercial for the fast food giant's Southwest Patty Melt surfaced today - and the 19-year-old’s cameo certainly makes for mouthwatering viewing.

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

The teenager can be 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 bun and its contents, unleashing a mane of long blonde locks.

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

Perspiration beads are visible as she fans herself off before tucking into more of her fast food purchase.

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