Kelly, 30, has been modeling for the past 10 years. She met her fiancé in a "dive bar" in South Beach, Miami. Kelly admits to being high-strung and obsessive, "athletic, bossy and silly." She enjoys scuba diving, running and traveling, and attended two years of junior college. Kelly and Jon recently had a "bad breakup on their three-year anniversary" over getting married, but since then, they've gotten engaged. Nothing's off limits in conversation. Kelly believes that she "could fit in at the presidential banquet or at a frat party," though Barbara Bush once told her at a VIP Texan party to "stay away from George." She gets motion sickness and fears spiders, bees, heights and sharks.

Originally from New Jersey, Jon, 28, is a real estate agent and has worked as a model and bartender in the past. He's an "all-around good athlete" and graduate of Rutgers University, which he attended on a Lacrosse scholarship. He enjoys skiing and boating and considers himself to be "spontaneous, competitive and funny." Jon claims to have no fears and he often blows off steam by playing football on the beach. He spent some time in Thailand with his teammate and has traveled to Italy, France, Holland, the UK and Portugal. He speaks no foreign languages. Jon describes Kelly as "very sympathetic for others," but admits that one of his pet peeves about himself is that he is extremely critical of other people.
