In a scene in the film, Katherine's character Abby has an orgasm at dinner with work bosses while wearing the buzzing underwear. However, Katherine was not much impressed with the bizarre contraption when she attempted to perk up her sex life at home.
"I took the vibrating pants home with me... I was being 'method', you know really committing to my role, but they don't work at all," the Sun quoted her as saying. She added: "That's not a solid purchase. Ladies don't bother!"
Katherine also said that she had never bothered faking an orgasm to please a partner. She said: "If it's not working it's not working. I'm not gonna go to all that bother to fake it - let's work this out together!"
