The 32-year-old singer - who shot to fame on 'The X Factor' in 2005 - credits the former Spice Girls star for helping him when he spiralled into drugs and alcohol addiction in 2013.
He told The Sun newspaper: ''Lots of people picked me up from my lowest... that includes my family and Mel. I know where I went wrong and I know I'll never go there again.''
The 'When We Collide' hitmaker previously revealed he was just weeks away from death and only realised he needed to seek help for his problems when he collapsed in the street, began stripping on a train and nearly choked on his vomit.
He said last year: ''I was so out of it - I was like a zombie. ''The doctor said to me if I'd been left to my own devices for another three or four weeks I might not be here now.''
After four weeks in the rehab facility The Priory last year, Matt managed to curb his addiction and is ready to focus on his music career and personal life.
