Professor Green, real name Stephen Manderson, has pleaded guilty to drink-driving at Bromley Magistrates Court.
The Mirror reports that the rapper has pleaded guilty to one charge and been fined £400, ordered to pay £40 court surcharge and £85 costs.
He has also reportedly received a 12-month driving ban, though this can be reduced if he takes a drink drive awareness course.
The Mirror adds that tests showed the rapper had a blood alcohol level of 52mg per 100ml of breath, exceeding the legal limit is 35mg.
The case relates to an incident which occurred in November 2013, when Manderson was arrested on suspicion of drink-driving after police were called to a suspected robbery in Lewisham.
When officers arrived at the scene at around 2.30am on 3 November they discovered a van and a Mercedes had been involved in a car crash.
Pro Green recently completed work on his third album, ‘Growing Up In Public’, which is scheduled for release on 12 May.
