Tulisa Contostavlos has claimed she was drunk when her infamous sex tape was made and could not remember her boyfriend Justin Edwards making the film.
In an eight-page witness statement to the High Court obtained by The Sun, the singer insists she must have been intoxicated during filming of the explicit footage.
According to the newspaper, her statement says: "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."
The 23-year-old, who secured a temporary ban on the raunchy footage after it went public online last month, claims her ex conducted a hate campaign to destroy her.
She adds: "Justin Edwards claims in a letter to his solicitors that I 'took many pictures and videos of us having sex' and I still have those videos. That is completely untrue."
She also denies allegations that the footage was taken in a public place, saying it was likely to have been filmed in her dressing room at an N-Dubz gig.
Tulisa is suing Justin, known as MC Ultra, in a trial set for this summer. He denies leaking the tape.
