Lee was arrested earlier this year after police caught him driving ‘erratically’ during the early hours of the morningon April 11.
According to reports, there was an empty bottle in the pocket of the driver’s seat.
Lee appeared in court to face charges. He turned up with his band mates Duncan James, Simon Webbe and Anthony Costa.
The prosecution told the court: ‘Officers could immediately smell alcohol from Mr Ryan's breath and his eyes appeared glazed.’
‘Asked if he had consumed some alcohol that night, Mr Ryan said 'Yes, a few'.’
‘Officers then noticed that there was an empty bottle in the pocket of the driver's seat. When Mr Ryan exited the vehicle, he was obviously unsteady on his feet, his speech was slurred.’
According to police reports, the singer then started swearing at police before they arrested him on suspicion of drink driving.
Police officers then held him in a cell, where he urinated on the floor.
Lee blames the abuse he received following his appearance on Celebrity Big Brother for his behaviour.
The arrest also came after ex-girlfriend Jasmine Waltz accused the star of being an alcoholic.
‘I know I've let people down. Being arrested and ending up in a cell was the biggest wake-up call to me.’
‘It made me realise there is a problem I can't keep ignoring. I need to do something about it.’
Lee is reportedly receiving treatment to combat his demons.
‘I am doing this because I have finally admitted I need help. I want to stop hurting the people around me.’
