The 16 year-old said despite his mum Pattie's faults, she managed to turn her life around for him.
He told British newspaper The Guardian: 'My mum wasn't the greatest person. I mean, she was a good person, but she made mistakes, she drank, she probably did drugs and stuff, and she told me about it because she said she did enough bad stuff for the both of us.'
The U Smile singer added: 'I don't need to do it because she already did it. The fact is, she changed her life around because of me. When I was born she quit smoking, she quit drinking - she did that all for me.'
