Sports Illustrated stunner Hannah Davis was turning up the heat in Hollywood as she helped encourage Californians to visit Las Vegas this summer. She might be used to modeling skimpy swimwear but the beautiful brunette proved she looks just as hot with her clothes on in a bright white crop top and skirt combo. Attempting to counteract her hotness the 25 year old handed out ice creams to the boiling crowd. Joining Hannah to get the party rocking was former Hills star Brody Jenner who hit the decks. The son of Caitlyn Jenner was rocking his usual laid back Californaina look in a grey tee, jeans and a baseball cap.
