N-Dubz star and X Factor judge Tulisa Contostavlos has confessed to being so drunk when she was filmed having sex with her ex-boyfriend, that she forgot it ever happened.
The singer made a statement during legal proceedings into the sex tape last month and details have recently emerged.
"I believe I must have been intoxicated at the time the video footage was taken," said the singer, reports The Sun newspaper. "'Now that I can see the video, I can see it is me in it."
"I must have been very drunk to let my then boyfriend Justin Edwards, who I also know features in the video, take the footage.
"It must have been in a private dressing room or toilet in a dressing room. My dressing room always had the door locked and there was security outside. It looks like I was at an N-Dubz gig."
Tulisa premiered her first solo single, 'Young' shortly after the sex tape appeared online.
