Despite strong denials from her record company, N-Dubz singer Tulisa Contostavlos has confessed that it was her seen in a recently leaked sex-tape.
The singer and X Factor judge claims to have been 'betrayed' by an ex boyfriend, calling himself MC Ultra, and apologised to fans in an online video.
"I am devastated, heartbroken," she said. "When you share an intimate moment with someone that you love and trust you never imagine for one minute that footage may at any point be shared with the rest of the UK."
