Tulisa's Ex-Boyfriend Vows To "Speak Up" About Sex Tape
MC Ultra plans to tell his side of the story regarding the saucy clip...
The 23-year old also claimed she was aware that Edwards was threatening to make the raunchy tape public, after a mutual friend warned her six months ago that Justin had "been threatening to bring it out to ruin my career."
Contostavlos added that she was "devastated" and "heartbroken" that the video had been leaked, stating she also felt "deeply betrayed" by Edwards.
Responding to The X Factor judge's confession, Justin - whose Twitter followers have rocketed to a few thousand over night - has vowed to "speak up" and reveal his side to the story.
He tweeted: "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 (sic)."
A few hours later, Edwards added: "To find the truth both sides of the story should be heard b4 passing judgement #thatisall."
Justin had previously commented on the leaked footage of Tulisa, telling his followers in the hours after the tape was made public: "I didn't wanna say anything on the subject but I see peoples imagination running away.. it's nothing to do with me. #backtowork."
He added: "Keepin my twitter quiet outta respect for a certain someone no other reason than that."
