When we last caught up with Katherine Webb, the former Ms. Alabama USA was competing against Chrissy Teigen for the honor of being Spike TV's new girlfriend. It took a couple months, but Katherine has recovered from the Spike TV rejection (Chrissy won) and will be the newest SI Swimsuit model to appear in a Carl's Jr. ad, where she will promote the Buffalo Blue Cheese Thickburger.  Webb joins Nina Agdal, Heidi Klum and Kate Upton as swimsuit alums who promoted the fast food chain. In honor of Webb, here’s a look back at SI Swimsuit models supporting Carl’s Jr. and Hardee’s.
