Sara Jean Underwood and Emily Ratajkowski recently did a photo shoot promoting Carl's Jr.'s newest menu item, the Memphis BBQ Burger. However, while the burger looks appetizing, it's the image of the two as naughty cowgirls that guys will be feasting on.

The fast food chain's move to cast two of the hottest (occasionally nude) models for the new campaign wasn't their most risqué one by any means. The company's built a reputation on hiring the hottest and most scandalous women to promote their product. They've previously worked with Kim Kardashian, Kate Upton, Olivia Munn, Audrina Patridge and Paris Hilton.
