Red Carpet Wedding: Deanna Burditt and Rick Harrison

Reflecting on his Sunday wedding to fiancée Deanna Burditt, Pawn Stars's Rick Harrison tells PEOPLE it was "the happiest time of my life." But as with all weddings, not everything went as planned. "I was so nervous that [when Deanna] went to put the ring on my finger, it didn't fit," says Harrison, whose big day was officiated by Counting Cars star Danny Koker. "I'd put out my wrong hand!" Harrison lost his ring two days before the wedding and spent the three hours pre-ceremony running around town to get a replacement he'd shipped from his pawn shop. "It's almost identical," he says of the new band.
