The court played out a phone call which heard Mahmood promise Tulisa she would "certainly be (there)next year at Cannes (Film Festival)", if she helped supply cocaine.

Cray added: "This was a Sun newspaper sting and she fell for it, but we say she then went on to supply the cocaine, in real life, in the real world."

It was argued that althoughTulisa's friend, rapper Mike Coombs, was the one who actually delivered the drugs to the reporter, she was 'instrumental' in arranging the deal.

Tulisa denies the charge of being concerned with the supply of class A drugs, with the trial ongoing.

Coombs pleaded guilty to supplying cocaine, and will be sentenced once proceedings against Tulisa are concluded.
