Rapper Dappy is desperate to track down Tulisa Contostavlos' ex-boyfriend Justin Edwards to confront him over her sex tape scandal.
N-Dubz star Constostavlos hit headlines in March when footage of her performing oral sex on Edwards was leaked online, and she later accused him of releasing the film.
Now her bandmate and cousin Dappy - real name Costadinos Contostavlos - has spoken out in support of the singer, insisting he can't wait to take Edwards, also known as MC Ultra, to task over the incident.
He tells Celebs on Sunday magazine, "I can't wait to catch that guy, MC Ultra, who sold that sex tape. He was her boyfriend for four years. They decided to do something nice together and keep it on the phone, for themselves.
"He's an idiot. She left him because he was a right softie and she wanted a real man. I remember the day he was crying like a little baby when we were on tour. A year later he sold the tape and got his little pay cheque. So well done."
