Tulisa Contostavlos has finally broken her silence after a video that allegedly showed her performing a sex act was leaked on the internet.

The N-Dubz star had stayed quiet since the scandal broke on Monday - but she's now back on Twitter after a 2-day break.

'Chilllng with @garethvarey and @nyofficial. Time to woop some ass on mario kart!!!!' Tweets Tulisa, 23.

The X Factor judge is yet to make any reference to the graphic 6-minute clip that features a blonde girl giving a man oral sex backstage at a concert.

But some of her 1,719,518 Twitter followers had a lot to say on the subject.

'Does the winner get a blowjob?' Tweets one fan in reply to Tulisa.

Another writes: 'Can you send me the link to your sex tape? Yet to see it, I feel left out!'

Tulisa's rep Simon Jones has told Now Online: 'Tulisa has asked us not to comment on speculation about her personal life.'
