Josh Kelley: Katherine Heigl Is Leading Wedding Planning
"I'm kind of a part of it," Kelley says about the nuptials. "But I think she's got a pretty good handle on it."
Of his offer to help, he tells PEOPLE: "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!"
Asked if the music set list will include his song "Only You," which might be nostalgic for the couple who met while filming the song's video, the singer seems unsure.
"No, probably not," he says. "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!"
Kelley, 27, and Heigl, 28, who stars on Grey's Anatomy, got engaged in June 2006. In September of this year, Kelley told PEOPLE, "I'm ready to settle down, start a family and build my Kelley empire."
His new album, Special Company, is out Feb. 5.
