Katherine Heigl's husband gets jealous when she kisses her co-stars.
The 30-year-old actress has revealed musician Josh Kelley hated watching her sexy scenes with Gerard Butler in upcoming film 'The Ugly Truth'.
When asked if Josh was comfortable with her getting intimate with the Scottish actor, Katherine said: "No, not really. It's not his favourite part of the profession but I told him, 'It's my job, and if I feel uncomfortable doing my job, and it suffers because of it, I'll kill you.' "
This is not the first time Katherine and Josh have had disagreements.
When they first moved in together, the couple argued constantly.
Katherine explained to Britain's Marie Claire magazine: "Josh and I didn't live together before we were married because I wanted to hang on to those last days of my single-girl pad as long as I could.
"I'm not going to lie - it was rough when we finally moved in together. It's the simple stuff everyone talks about. I like things neat, he leaves things everywhere."
But no matter how angry Josh gets, Katherine says she is "not ready" to stop doing romantic comedies.
She explained: "I know I'm catching some c**p for only doing romcoms, but I really like doing them. People keep asking me if I want to do anything more serious, or Oscar-worthy, and I do, but I'm not quite there yet.
"I did a lot of heavy stuff in 'Grey's Anatomy'. My mother went through breast cancer 12 years ago, and it brought a lot of that back. I don't want to do that 24/7."
