Ex-lover denies leaking Tulisa Contostavlos tape A former boyfriend of singer and TV talent show judge Tulisa Contostavlos denies posting a sex tape showing the couple sharing an "intimate moment," a High Court judge was told today. Justin Edwards thought the posting of such material "ungentlemanly" and said he had been "brought up better than that," Mr Justice Tugendhat heard. Edwards said Contostavlos had "persuaded me that we should film ourselves" and "seemed to be implying" that filming took place on the singer's phone, the judge was told. Contostavlos, 23 - who shot to fame as a member of hip hop group N-Dubz and is a judge on the X Factor talent show - took legal action against Edwards following the emergence of the footage. She alleges that Edwards committed a "vindictive act of betrayal" out of spite and greed. Detail of Edwards's defence to the allegations emerged at a preliminary High Court hearing in London. Mr Justice Tugendhat said today that an order banning publication of footage showing Contostavlos "engaged in a sexual act" should continue. The order was made earlier this month after Contostavlos began legal proceedings. Edwards, a rap artist who performs under the name MC Ultra, was at today's hearing. Contostavlos was not in court. The judge was told that Contostavlos and Edwards had been in an "on and off relationship" which ended in late 2009.
