Kate Winslet has admitted that filming sex scenes leaves her feeling "sick".
The mother-of-two has stripped off for a number of films, including the blockbuster hit Titanic, where she wore nothing but an elaborate necklace under the watchful eyes of Leonardo DiCaprio.
She is currently starring in Little Children as a disenchanted mother who has an affair with her friend's husband, played by Patrick Wilson.
Speaking on BBC Radio 1, Winslet said: "When you get up in the morning and you know you are going to have to go to work and take your clothes off it's the worst day of your life.
"You feel awful. You feel sick. And you remind yourself you must never agree to do this again," she said.
But although she may hate filming the scenes, she told the Daily Mail that the scenes were "beautifully written".
"It's not just about having sex in these chaste, forbidden moments, it's about these two people being emotionally unveiled and unleashed through this physical affair," she said.
Little Children premiered at the London Film Festival on Wednesday night.
