Tulisa Contostavlos has been caught setting up an £800 (about R10 400) cocaine deal.
In a taped investigation, the N-Dubz star admitted she could supply the class A narcotic to an undercover journalist.
She told The Sun on Sunday's secret reporter: “Half my phone book sells it. Of course I can get it for you.
“Half the guys I know are drug dealers. One's a massive cocaine dealer. He's my best friend. He's a gangster - he's my gangster.”
The 24-year-old singer revealed the “lingo” she uses to help set up deals - with “green” and “white sweets” used as code for cocaine and cannabis
She said: “We talk in lingo. Like we know what. I can't call him and go, 'Have you got any?' I'll say, 'Hi, have you got any sweets?' ... And I'm referring to what he knows is what. Like we have a whole lingo.”
While the former X Factor judge said she doesn't take cocaine herself, when the reporter asked if she could get some for him she could “definitely” sort it out.
She told them: “Definitely on the day. What I'll do, I can definitely sort it - just got to make some more calls ... I have a number for a very good friend of mine to call when you would like your white sweets.
“He will sort you out immediately. You just say, 'Hi, it's Tulisa's friend and I'm calling about white sweets for me'. That's all you have to say.”
When the journalist promised to keep the deal a secret, she laughed: “I don't think it would sound too good if Tulisa was off finding white sweets.”
The newspaper revealed their findings have been passed onto the police.
A spokesman said: “We have received information concerning the alleged supply of illegal drugs at a central London location. We are considering the information.” - Bang Showbiz
