Singer Tulisa Contostavlos has been arrested on suspicion of drink driving after crashing her Ferrari, .
The former X-Factor star, 27, allegedly collided with a Saab outside a Tube station in Southgate, North London last night.
Officers were called and the singer was breathalysed at the scene and is believed to have failed the breath test. The star was then take in to custody in an East London police station.
A Met spokesman added: ‘Police were called shortly before midnight on Thursday to outside Southgate Underground Station following reports of two cars in collision.

‘Officers and London Fire Brigade attended. There were no reported injuries.
‘One of the drivers, a 27-year-old woman, was arrested on suspicion of drink-driving and taken to an East London police station.

The crash, which is understood to have been captured on CCTV cameras, happened at a roundabout outside Southgate tube station in north London shortly before midnight last night.
According to eyewitness, Mr Renz, the 27-year-old had been driving a black Ferrari California with yellow callipers on its brakes when she hit a Saab.
He added that Tulisa did not seem drunk, but appeared to have raced to the top of a hill leading to the roundabout, judging by the sound of the revs he heard.

When asked if the singer appeared drunk, he said: ‘She looked a bit normal. I didn’t understand why she accelerated to the top for no reason.’
Last year the former X Factor judge said she had been the victim of a ‘disgusting entrapment’  as she walked free from court after her drugs trial collapsed.
She punched the air in triumph as she was sensationally cleared of arranging a drugs deal after an undercover reporter who tricked her into boasting she could ‘sort out’ cocaine was found to have lied in court.
A police investigation was then launched into the Mazher Mahmood, the journalist who is known as the Fake Sheikh and has targeted a raft of celebrities, sportsmen and royals in tabloid stings.
The former N-Dubz singer had been accused of setting up an £800 cocaine deal, asking her friend Michael Coombs to take drugs to Mahmood after the reporter told her he was a ‘big shot’ movie executive offering her a £3million role in a blockbuster starring opposite Leonardo DiCaprio.
After a week-long trial she was cleared and said on the steps of court: ‘This whole case was an horrific and disgusting entrapment.’
