The 24-year-old former X Factor judge was exposed in an undercover investigation after it was claimed she was trying to supply the class A drug.
Tulisa compared the narcotic as "sweets" to a third party friend.
An undercover reporter for The Sun Online had asked her if she would be able to supply drugs to which she was quoted boastfully replying, "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."
"We talk in lingo", she said as she showed texts where she had made previous orders.
Tulisa added, "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 he'll be like, "Um, how many sweets do you want?"
"And I'll go, 'I want the green sweets', or I'll go - not for me because I don't do it, but for my mates - I'll go, 'I want the white sweets,' and then he gets it. And it's all codes."
