Singer Tulisa Contostavlos helped supply cocaine to an undercover reporter after he promised he could help her break into the movie business, a court has heard.

Sun on Sunday reporter Mazher Mahmood posed as a film producer and told her she could get a part in a film starring Leonardo Di Caprio.

Her rapper friend Mike GLC supplied the drug at London's Dorchester Hotel.

Miss Contostavlos denies helping to broker the drug deal.
