The singer and former X Factor judge, Tulisa Contostavlos has told the BBC she has never been involved in drugs and she has never taken cocaine.

She had been accused of arranging to supply cocaine to the Sun on Sunday's undercover reporter, Mazher Mahmood, who posed as a film producer.

In a separate case the singer was fined £200 for assault - she says she will appeal.

She has been talking to the BBC's arts correspondent, David Sillito.

Tulisa: The Price of Fame will be broadcast on BBC Three at 22:00 BST on Monday 28th July 2014.
