kateupton-mercedesKate Upton is no Charlie Tuna, not after Mercedes-Benz tapped her to tease the automaker’s Super Bowl ads before the game. She poses with the sleek new CLA sedan and supervises a sudsy bath to the sounds of a raucous jazz tune.

Wait, she’s not getting the bath, the car is.

Upton, 20, keeps it casual in a black spaghetti-strap top, a black bra and a tiny pair of Daisy Duke denim hot shorts. There’s no question about Kate’s star-power. The video was posted on YouTube four days ago and already has 3.8 million views.

During the spot, she runs through all her signature moves, tousling he hair, shaking her head and making little pouts with her luscious lips, as three handsome hunks scrub down her car at what looks like a high-school charity car wash.

Upton will also be featured in the Mercedes Super Bowl ad with singer Usher. The game will be played on Feb. 3.

Mercedes is pushing the CLA in the domestic market for the first time. It’s the brand’s entry-level, front-wheel drive car that will sell for about $30,000, according to The Los Angeles Times.

The car is targeting 20-something buyers who might not go for the boxier Mercedes C-Class sedans and goes on sale in September.
