Singer Josh Kelley can't wait to marry his actress fiancee Katherine Heigl - as long as he doesn't have to mastermind the event. The couple are due to wed on 23 December (07) in Utah, but the 27-year-old star insists he's happy to stay out of the way and let his Grey's Anatomy star wife-to-be arrange the whole ceremony. He says, "I'm kind of a part of it. But I think she's got a pretty good handle on it." "I said, 'Baby, you know, anything you want me to do, I got it.' But you know, other than that, what am I really gonna do? 'The tulips need to go over here?!' I don't know!" And Kelley has hinted he will perform his hit Only You at the ceremony - as the couple met while filming the song's video. He adds, "I might get up and play it, I don't know. Maybe I should tell the wedding band to learn that. That might be a good idea! Yeah, that's probably a good idea!"
