David Hasselhoff shouts encouragement to competitors as they compete in the Nautica Malibu Triathlon. Hollywood celebrities got together for a good cause and competed in the annual Nautica Malibu Triathlon on Sunday. Desperate housewife, Terri Hatcher competed for the Disney team. She looked a little worse for wear following the bike ride and needed a hand when she got out of the water from the long swim, but she pushed on through and finished with a run. Mario Lopez didnt mind showing off his muscles either, getting into his wetsuit, doing the swim, onto his bike and then finishing it off with a run. Jason Lee was also in attendance doing a Realy for his team, LA ROX and David Hasselhoff was seen watching the event from a podium.Â
