Tulisa Contostavlos is to be called in by the Metropolitan police after she was caught setting up a £800 cocaine deal during an undercover investigation.
A source has revealed the former X Factor judge will be questioned by officers from Scotland Yard's Major Crimes Unit "within days" after the 24-year-old star allegedly arranged for her friend to supply half an ounce of the Class A drug to an undercover reporter from The Sun.
A Scotland Yard spokesman told the publication: "We have received information concerning the alleged supply of illegal drugs. We are considering the information received."
A police car was spotted arriving at Tulisa's £6 million Hertfordshire home yesterday (02.06.13), where she reportedly spent the day after details of the investigation were revealed.
The singer and her team had at least six boxes of pizzas delivered and her N-Dubz bandmate and cousin Dappy Contostavlos was spotted arriving around mid-afternoon, hiding in the back of a red car.
During the taped investigation, Tulisa admitted she could arrange for cocaine or cannabis - which she refers to as "white sweets" and "green sweets" respectively - to be delivered for the reporter.
She said: "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.
"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."
When the journalist promised to keep the deal a secret, Tulisa joked: "I don't think it would sound too good if Tulisa was off finding white sweets."
The publication has passed its findings 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."
While Tulisa insisted she did not take cocaine herself, one top TV executive said it will be tough for the singer - who was axed as an X Factor judge last month - to recover her image following the investigation. They said: "It's going to be very difficult for her now."
