The arrests come after the Metropolitan Police said its officers were ‘’considering’’ information after a newspaper suggested Contostavlos had acted as a go-between in a drug deal by introducing a journalist to an alleged supplier.
According to report, half an ounce of cocaine changed hands as a result of the deal conducted at London’s Dorchester Hotel.
A spokesman for the Met confirming the arrest said officers from Westminster have today, arrested two people – a 35 year-old man and a 24-year-old woman – by appointment at a central London police station.
The 24-year-old singer, who found fame with N-Dubz whose debut solo album made it to only number 35 in the charts – won an apology last year from a former boyfriend who leaked footage on to the internet of the two of them performing a sex act.
In reaction, Contostavlos’ spokesman declined to comment on the development.
Contostavlos was officially dropped as a judge on The X Factor just days ago, with Sharon Osbourne returning to the show in her place.
