Katie and Marc first met in 2001 at a karaoke bar. "I thought he was a handsome babe, so we got to chatting— must've been feeling very confident, because he leaned in for a kiss," Katie says. "I told him that it wouldn't be that easy, but that I'd consider a kiss after he sang a song. He went onstage and sang 'Sweet Caroline'—it was seriously the best performance I'd ever seen. It won me over and we've been together ever since." On their wedding day, Katie wore a Monique Lhuillier gown with silk organza ruffles on the bodice and skirt, purchased from the designer's salon in Los Angeles.
