Keira Knightley has confessed she couldn’t stop laughing while filming a love scene with Dominic Cooper for her new film The Duchess Showbiz Spy report. “Sex scenes are never the easiest scenes to film and you are meant to be very supportive of each other,” the actress explains. “But when Dominic came out in a skin-coloured nappy I just completely lost it. I just couldn't stop laughing. The director did actually come over and said: 'Come on, pull yourself together, this is a serious work here' but I could not help it - there was this man standing there in a skin-coloured nappy!”
