Josh Kelley: Marriage to Katherine Heigl Is 'Unbelievable'

"It's feels unbelievable to be married. I thought that [being married] wasn't that different [from dating], but actually it is so different," the singer-songwriter, 28, told PEOPLE during his album party last Thursday at Chicago's Rockit Bar and Grill. As a husband, "my mentality changed from being a boyish man to a man's man."
In fact, his courtship with the Grey's Anatomy star, 29, has been a crash course in emotional maturity.
"When we first met, I could tell that my A.D.D. would definitely frustrate her a little bit," Kelley confessed. "It's like, I would be drawing on paper tablecloths when I should have been engaging in conversation – little things like that. No one ever told me that before. Nobody ever cared. But she does. And I like that."
The two – who didn't live together until after the ceremony – have settled easily into a domestic routine. (Heigl has had plenty of time to nest, thanks to the writers' strike.)
"We cook together," he said. "She is a great cook. I am a good helper-chef. I'm good with the grill and good with taking chances with certain spices."
What about hitting the L.A. club scene? "We are not a typical Hollywood couple at all," Kelley explained. "We stay in. We cook, we watch Dexter, and I make music and paint. It's fun."
