Leslie Mann has admitted she couldn't wait to kiss Nikolaj Coster-Waldau while they were filming The Other Woman.
Knocked Up star Leslie is married to director Judd Apatow in real life, but played Game Of Thrones actor Nikolaj's character's wife in the comedy about a triple-timing love rat.
According to Collider, she revealed: "I was super excited to make out with the hot guy from Game Of Thrones.
"I've been married for 17 years and you know how the actors say, 'It's really technical. Those scenes are not sexy. They're just so technical. It's like work.' And I'm like, 'That's b*******.' Believe me, it was really exciting.
"I was so excited to make out with him. And then, we did the kissing scene, and I broke out into full hives, and they thought maybe it was his aftershave.
"We did it again and I broke out into hives again."
Nikolaj pointed out that it hadn't been a problem with another of his co-stars, Cameron Diaz: "It didn't happen with Cameron though."
Cameron agreed: "No, I have a sturdy constitution."
But Leslie said she had remained committed to the scene despite her allergic reaction: "I finished the job. I got the job done."
The Other Woman is released in cinemas on April 25.
