Check out Kate Upton's sexy Super Bowl commercial for Mercedes-Benz [Video]

It sounds like the perfect Super Bowl commercial: A hot model soaps up a car while wearing short-shorts and a tiny black tank top.

Well, that's not quite what we get in Mercedes-Benz's sneak peek at its upcoming Super Bowl commercial. While the video is labeled "Kate Upton Washes the All-New Mercedes-Benz CLA in Slow Motion," the curvaceous Sports Illustrated babe doesn't actually do any washing.

Instead, the 21-year-old Upton shows off her famous assets in the aforementioned shorts and tank top for a bunch of googly-eyed football players who do the washing for her.

This isn't Upton's first high-profile commercial highlighting her sexiness. In a Carl's Jr. ad, she donned sheer black stockings and writhed around in a car while eating one of the fast-food chain's burgers.

It seems Upton is this Super Bowl's coveted model. Last year, Victoria's Secret angel Adriana Lima starred in two commercials for Kia Optima and Teleflora. Over the years, models have appeared in many memorable ads -- like the classic 1993 Pepsi commercial with Cindy Crawford.
