Grime MC Big Narstie has offered his two cents on the undercover sting that caught pop star Tulisa acting as a go-between on an £800 cocaine deal.

“You wouldn’t meet an occasional stranger and talk about your fanny, ‘cos you’d say that’s too intimate to talk to someone about,” Narstie says in a video by GrimeReportTV.

“So if we’re talking about drugs, why would you give a stranger your x-man’s number?”

Reacting to the X-Factor judge’s brag that her phonebook was full of drug dealers, he added: “The only thing she left out was her knicker size and her bra. Everything else is on the streets.”

Narstie also demonstrates the proper way to take ‘green sweets’ – Tulisa’s not-very-cryptic codeword for cannabis – by shoving some lurid-coloured Chewits sweets in his mouth.

Final verdict: “Everyone needs to just get normal jobs and just behave themselves.”
