British actress Katherine Kelly has wed her longtime boyfriend in Las Vegas. The star, who appears opposite Jeremy Piven in U.K. drama Mr Selfridge, jetted out to Sin City to exchange vows with boxer Ryan Clark - without telling her family. They decided to get married during a vacation to the resort, and headed to the city's fabled Little Church of the West on 20 August (13) for the impromptu union. She tells Hello! magazine, "We wanted to enjoy the day without all the usual planning and pressure. We just wanted to let it roll, so it had an on-the-run feel to it. "We'd been laughing and joking all day and then suddenly everything seemed to stop and we tried to get the words 'I do' out without becoming emotional wrecks. It was awesome. I'll never forget that moment for the rest of my life."
