Joanna Page has revealed she didn't want to give back the prosthetic bump she wore while filming Nativity 2.
The actress - who recently announced she is expecting a baby with her husband, Emmerdale's James Thornton - donned the prop to play a mum-to-be in the festive movie.
And she confessed: "It was fantastic because it was really warm. When we were filming it was freezing cold and I had this massive big plastic thing which stuck straight onto my skin, so you can imagine how much you sweat in it.
"They'd say, 'Do you want a little cashmere thing to put between your skin and the bump?' and I'd say 'No, I really like it when it gets hot and sweaty and it sticks to me, because it just makes me warmer'.
"It was really nice and warm. I could have kept it and used it as a hot water bottle."
Joanna - who said she is "just very happy and excited" about her real-life pregnancy - stars alongside David Tennant and Marc Wootton in the film, the follow-up to 2009's Nativity.
She said of her on-screen husband David: "He's really, really lovely. All the film was improvised, David was brilliant to work with, really exciting and interesting, and a really laid-back, funny fella. I was laughing a lot."
