Tulisa Contostavlos has been arrested by police on suspicion of supplying a class-A drug.
The 24-year-old singer, who found fame with N-Dubz, was arrested along with a 35-year-old man by appointment at a central London police station and they both remain in custody.
The arrests come after the Metropolitan Police said its officers were ”considering” information after she was allegedly caught out by an undercover reporter for The Sun on Sunday acting as a go-between in a drug deal.
The Sun On Sunday reported that half an ounce of cocaine changed hands as a result of the deal conducted at London’s Dorchester Hotel.
A Met Police spokesman said: “Officers from Westminster have today, Tuesday June 4, arrested two people – a 35 year-old man and a 24-year-old woman – by appointment at a central London police station on suspicion of being concerned with the supply of class A drugs.
“They remain in custody at a central London police station.”
Tulisa’s spokesman declined to comment on the development.
The singer was officially dropped as a judge on The X Factor just days ago, with Sharon Osbourne returning to the show in her place.
The star – 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.
