X Factor judge Tulisa Contostavlos league of sex tape stars an X-rated video, allegedly featuring her emerged online.

The seven minute clip, which features a blonde resembling the singer before her X Factor makeover performing a sexual act, caused a media frenzy after it was uploaded onto a paparazzi website.

Users flocked in their millions to watch the video, which was reportedly filmed on a Blackberry handset more than two years ago, and post their views.

Contostavlos publicly addressed rumours of a sex tape in August last year when an unnamed man was reportedly trying to sell the explicit footage for a staggering £5000, 000.

At the time she insisted that it she was 'horrified' about the 'fake' tape and categorically denied ever filming it.

The 23-year old singer has now called in her lawyers to deal with the situation while she keeps tight-lipped about the scandal.

The Daily Mail reports that Contostavlos' lawyers have issued an injunction banning any description of the act in the alleged footage.

However, while she received some media backlash, some commentators suggested that the leak could in fact help the singer who is currently embarking on a solo career.

One Twitter user named @ceesway even advised: ""Release ur single 2day Tulisa,"

Due to the global media interest that the leaked video generated it is safe to say that it has successfully made a household name.

She has now joined the growing line of celebrities from actors to singer, who have had incriminating videos of themselves making the rounds on the internet.
