Singer and former X Factor judge Tulisa Contostavlos has been arrested on suspicion of supplying class A drugs.
The arrest comes a day after the Metropolitan Police confirmed it had "received information concerning the alleged supply of illegal drugs at a central London location".
It follows a report in a tabloid newspaper that suggested Contostavlos acted as a go-between by introducing a journalist to an alleged supplier.
The 24-year-old is said to have boasted to the reporter: "Half my phone book sells it. Of course I can get it for you. Half the guys I know are drug dealers."
The Sun On Sunday claimed half an ounce of cocaine changed hands following a deal that took place at London's Dorchester Hotel.
Contostavlos's management is yet to comment on the claims.
