Tulisa Contostavlos' ex admits uploading sex tape

Tulisa Contostavlos' ex-boyfriend has admitted leaking a sex tape of the singer online.

N-Dubz star Contostavlos was left distraught in March when a clip of her engaged in an intimate act with former partner Justin Edwards circulated on the internet.

During a hearing at the High Court in London on Monday, Contostavlos' lawyer Jacob Dean confirmed Edwards had uploaded the video to the web despite initially insisting he was not involved, according to The Sun newspaper.

Dean tells judge Mr Justice Tugendhat, "Mr Edwards has admitted responsibility for the video, apologised for it and promised not to do it again."
