MC Ultra, the man alleged to feature in a leaked sex tape featuring Tulisa Contostavlos, has appeared to respond to claims that he "betrayed" his former girlfriend.

X Factor judge Tulisa issued a heartfelt confession after a sex tape which alleged to feature the N-Dubz singer surfaced online.

She later admitted her part in the clip and also claimed that the other party was former boyfriend and grime artist MC Ultra.

MC Ultra took to Twitter to seemingly share his thoughts on the issue, declaring that he is going to have "speak up and lay out the facts". He said:

"I believe in silence being a sign of Integrity but in this case I guess I'll have to speak up and Lay out the facts and let you guys decide."

He then tweeted this morning (March 22): "To find the truth both sides of the story should be heard b4 passing judgement #thatisall."
