Lawyers representing British X Factor judge Tulisa Contostavlos have issued an injunction on any description of an alleged sex tape featuring a woman reported to be the singer and TV star.

The seven-minute tape popped up briefly via website before it was removed on Monday, and the 23-year-old pop star wasted no time in getting her legal team on the case.

Representatives for Contostavlos denied reports suggesting the singer had recorded a sex tape last year, when it was first offered to media outlets.

A spokesperson for the star said, "This tape is 100 per cent fake and is just someone trying to cash in on her X Factor role. She is horrified that someone would go to the extreme lengths of fabricating a video. It is absolutely not her. Tulisa has categorically never allowed anyone to film her having sex." bosses have confirmed they took down the sex tape footage after receiving a cease and desist letter from Contostavlos' lawyers.
