Hollywood actress Mischa Barton has fallen for another rock star – she is dating British singer Luke Pritchard. The former O.C. star has had a string of failed relationships with musicians, including Cisco Adler and Rooney guitarist Taylor Locke. But she has not been put off dating rockers, and is now stepping out with Pritchard, frontman of U.K. band The Kooks. And he insists he isn’t phased by Barton’s poor track record with musicians – because he’s thrilled to have a relationship with the actress. He tells Britain’s Daily Mirror, “It’s early days yet but, yes, we are seeing each other. I’m very lucky. She’s beautiful, so I feel lucky she decided to go out with someone like me. It came about because we have lots of friends in common and kept going to the same parties.”
