Lee Ryan says his arrest has been a big "wake-up call".
The Blue singer was arrested on Friday (11.04.14) on suspicion of drink driving and later charged with failure to provide a specimen and criminal damage, has admitted he has "let people down".
He told the Daily Star Sunday newspaper: "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."
It was confirmed yesterday (12.04.14) that Lee - who was also found with a controlled substance in his possession - will be going to rehab to help him overcome his persona issues.
He added: "Me going to rehab isn't a cop-out. I still take full responsibility for the way I've behaved.
"There is nobody to blame but myself and I'm deeply ashamed of what has happened.
"I am doing this because I have finally admitted I need help. I want to stop hurting the people around me."
