Keira Knightley held up the filming of a sex scene in her new film The Duchess - because she found her male co-star's flesh coloured nappy too amusing.
The unflattering attire was meant to cover up Dominic Cooper’s manhood during a love scene with Keira's character, however the actress could not stop laughing when she saw her fellow actor.
“You are meant to be very supportive of each other, but he came out in a skin coloured nappy, and I just completely lost it,” the actress tells us.
Her hysterics got to the point where director Saul Dibb had to step in and give her a telling off: "Saul actually did come over and say ‘come on, just pull yourself together, this is serious work,’.”
You can see Keira and Dominic (minus nappy) in The Duchess from September 5th.
