Giuliana and Bill got engaged on Dec. 15, 2006. A limo met Giuliana at the Chicago airport and whisked her off to a nearby helipad, where Bill was waiting — with her favorite pizza and a bottle of champagne. He waited until they were flying over downtown Chicago — with all the holiday lights on display — to propose. "Bill told me we were going to look at Christmas lights," the E! News host gushed about the surprise!
