The former X Factor judge Tulisa Contostavlos has been bailed after being arrested for the supply of class A drugs.
She had been accused over the weekend by a newspaper, who said she had introduced their reporter to a drug dealer.
It was claimed the drug dealer then sold half an ounce of cocaine to them at London's Dorchester Hotel.
Tulisa's management declined to comment.
Asked about reports that Tulisa Contostavlos had been arrested the Met Police said: "Officers from Westminster have arrested two people - a 35-year-old man and a 24-year-old woman - on suspicion of supplying class-A drugs.
The police have since confirmed that both people have been bailed, pending further inquiries, until a date later in July.
The 35-year-old man questioned with Tulisa is a rapper known as Mike GLC he told Newsbeat "we're innocent and what else is there to say"
Tulisa recently confirmed on her Twitter account that she would no longer sit as a judge on ITV's The X Factor.
The 24-year-old added: "I'd like to thank everyone on The X Factor for two amazing years."
X Factor says "the two stories are unconnected".
Tulisa's private life has made the news in the past, including when the singer took to YouTube to make a statement about a leaked sex tape. At the time, Tulisa described the experience as "devastating".
