Paris Hilton Returns in Steamy Carl's Jr. Ad With Bikini-Clad Sports Illustrated Model Hannah Ferguson: Exclusive Picture

These ladies sure love "Texas in the springtime." Nearly a decade after her original commercial, Paris Hilton returned for yet another steamy Carl's Jr. ad, and this time she brought along a friend—Sports Illustrated model Hannah Ferguson

The bikini-clad gals munch on a Texas BBQ thickburger, but it's 22-year-old Ferguson that gets soapy during the commercial. Hilton, 33, makes a quick cameo toward the end, quipping, "You missed a spot."

The hotel heiress first stripped down for a Carl's Jr. ad in 2005. The commercial was banned from TV at the time for its over-the-top sexual nature.

The Carl's Jr. spokesperson said earlier this month that she still indulges in fast food, but lost five pounds by making healthier choices. "There are times when I will stop at a Carl's Jr., but I will maybe get a turkey burger or something healthier instead of a cheeseburger and fries," Hilton told the Daily Mail. "I am more careful now."
