X Factor Judge Tulisa Contostavlos has become a hot internet topic after an explicit sex tape allegedly featuring her was leaked online.

Fans of the 23-year-old singer have headed to Twitter and FaceBook to voice their opinions on the footage, which is currently making the rounds on the internet.

The seven-minute clip, featured on pappzd.com, allegedly shows Tulisa engaging in a sexual act, reportedly recorded on a BlackBerry handset before she got her big X Factor break.

One Twitter user named @AndrewBloch wrote: "Tulisa should have known these things always N Dub on Twitter."

Another commentator said: "Tulisa didn't think the video would N-DUB on the internet. She isn't DAPPY at the moment but she's got money so I guess it doesn't FAZER"

Others meanwhile advised her to use the bad publicity to promote her solo career.

"Release ur single 2day Tulisa," @ceesway advised.

This is not the first time that the X Factor judge has been haunted by the tape. In August last year, the X Factor judge was targeted by unnamed man who was trying to sell the tape for £500,000.

A spokeswoman for the singer told IB Times UK that she had "no comment whatsoever" when asked about the video.
