The alleged sex tape of X Factor judge Tulisa Contostavlos is still being hosted online after her lawyers took action against some websites. The singer has said that the tape is a fake, but many are still wondering if it is Tulisa or not.

The racy video can be found through a link on the website StupidCelebrities.net, which shares the tape from another website.

News of Contostavlos' alleged sex tape leaked online on Monday. The seven-minute long video shows a woman engaging in oral sex with an unidentified man. The Daily Mail has reported that the woman in the video resembles the 23 year old who sang with N-Dubz singer. The British website claimed that the blonde hair woman in the video resembles the singer during her days before the X Factor makeover.

The website StupidCelebrities claimed that the man in the video is Contostavlos' ex-boyfriend, MC Ultra. However, it is all just speculations, as that same website noted that Contostavlos' rep has denied that the sex tape is of her client, stating.

This tape is 100 per cent fake and is just someone trying to cash in on her 'X Factor' role, the website quoted the rep. 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.

Contact Music reported that the sex tape was allegedly filmed backstage at a gig. It also issued a new report on Tuesday, noting that Contostavlos' former bandmate, Dappy, allegedly took to his Twitter account claiming that the alleged sex tape is real.

When news of the sex tape hit the Internet, Contostavlos' lawyers swiftly moved into action to rid websites of the fake video. The BBC reported that an online magazine has claimed that the singer's lawyers forced the take down of a link to the alleged sex tape.

Nadia Kavahita, co-owner and editor of Pappzd magazine, told the BBC that they were shocked when the lawyers came to their office. Kavahita said they were given a deadline to remove the video or face further action.

We had no choice but to take it down, Kavahita said.
