Tulisa Contostavlos has claimed she was drunk during the filming of the sex-tape that was leaked last month.

The X-Factor judge, who revealed all about her ‘intimate moment’ with then boyfriend Justin Edwards in a YouTube confession last month, had previously denied any knowledge of the video existing last year.

But in an eight page witness statement to the High Court obtained by The Sun, the 23-year-old claims the reason why she initially dismissed reports about the tape was that she couldn’t remember making it:

"I believe I must have been intoxicated at the time the video footage was taken. 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.

"I was unsure whether it really existed. I was, however, suspicious of Justin Edwards. He admitted taking footage of me on his mobile but said he deleted it before he sold the phone. I had, and still have, no recollection of such footage being taken. He became uncomfortable when I asked what the footage was. I was scared someone might have it."

The Camden singer, who is suing the grime MC for £100,000 over the incident, also revealed the footage was probably filmed in a dressing room backstage at an N-Dubz gig, and claimed Edwards’ ex-girlfriend had previously warned her about his plans:

"She said he used to say he would wait until I became big, then release it to make money. I believe Justin Edwards is a manipulating and bitter man. He has a jealous vendetta against me. This video is part of a plan to damage my life and career."
