Amelle, 29, was pulled over by police in 2010 the morning after a heavy night and was later banned from driving for 14 months.
The singer was also ordered by magistrates to pay a £2,000 fine after admitting the offence in court.
As the festive season gets underway, Amelle has now told her story in the hope of alerting other drivers to the dangers of driving while over the limit - even the day after the night before.
Speaking on ITV1's Daybreak today (28 November), Amelle said: "I got pulled over, [I] literally didn't think anything of it.
"It didn't even cross my mind [that I might still be over the limit] it was just a horrible feeling, even when they said 'yes you're over'.
"Just the shame of it and that something could actually happen... Obviously I'd never leave a bar and get straight into my car - that's just something I would never do."
But Amelle added: "I was just slightly over, but that's not the point. I was over and I had to accept the consequences.
"I think so many people don't actually realise. This probably happens everyday to so many people."
Amelle warned motorists that people knowing what she did was a "horrible" feeling, however it would be a much worse feeling if she'd caused a fatal accident.
