Speaking to OK, the actress stated that even though her husband and her Life As We Know It co-star Josh Duhamel are good friends, Kelley still refused to visit the movie's set on days that she filmed romantic scenes with the actor.
"Actually, he and Josh Duhamel are good friends, but he would never come to the set when Josh and [I] had to like, kiss or make out," she said.
Heigl continued: "It does make him uncomfortable because he's not an actor, he's a musician. He always says to me, 'How would you feel if I had to make out with some girl in a video?'.
"And I'm like, 'If you have to do it, you have to do it. But I wouldn't want you to come home and tell me what a great kisser she is and I should try her technique.'"
Life As We Know It debuts in US cinemas on Friday.
