Despite desperate claims from Tulisa’s management that the sex tape is a fake, former N-Dubz star Dappy has taken to Twitter to announce the tape is real and the ‘mystery man’ is Fazer.

Dappy tweeted: “JUST SO EVERY 1 KNOWS,ME AND FAZER HAVE F…ED MANY B.TCHES 2 GETHER,SO I AM CLEARLY STATING THAT THE D..K IN T’S ALLEGED SEX TAPE IS FAZERS”.

In another tweet, Dappy wrote: “SECOND OF ALL, THAT WAS MORE THAN THREE YEARS AGO WHEN FAZER TOOK THEM PICS..THIS IS SIMPLY @IamFazer TRYING 2 GET @officaltulisa BACK! NUFF SAID!

Dappy has since deleted both tweets.

There are suggestions Dappy’s account was hacked into, however, he hasn’t said so. Fazer has also been quiet.

Meanwhile, Tulisa’s team is strenuously denying any authenticity of the sex tape.

A Tulisa rep said the tape: “Is 100 per cent fake and is just someone trying to cash in on [Tulisa’s] X Factor role.”

The rep added: “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.”
