Mark Evans admits he wasn't a good father to Adele as she was growing up and says that alcohol took over his life.
"I was an alcoholic and rotten dad to Adele. It tears me up inside. I was putting away two litres of vodka and seven or eight pints of Stella every day.
I drank like that for three years. God only knows how I survived it. I was deeply ashamed of what I'd become and I knew the kindest thing I could do for Adele was to make sure she never saw me in that state."
Despite keeping quiet about his past, he says, "It's time I got it off my chest. I've never talked to anyone about it before, not even my closest friends."
"I hit the bottle so hard that I am pretty much oblivious to anything that happened to me for three years. I was way, way below rock bottom by then. I reckon I made Oliver Reed look like a teetotaller.
I was in the darkest place you can imagine. I saw no way out. I didn't really care whether I lived or died. And all the time I thought, 'How can I do this to Adele?'…all I could do was drink and I'm so, so ashamed of myself for that. I was in so much grief that I couldn't see past myself and how I was feeling.
I was not there for my daughter when I should have been and I have regretted that every second of every day to this moment now. It tears me up inside."
Mark also says that it's too painful to even listen to any of her music.
Adele says she hasn't spoken to her father in years, however Mark says those are "lies" to protect him. He claims that she "forgave" him and that they speak on a regular basis now, adding:
"Adele still comes back to Wales to see us and I pop down to London every couple of months to meet her. The last time I saw her was about six weeks ago. We get on fantastically now so who knows, one of these days I might even find the courage to see one of her shows.
I am the proudest dad in the world. I think she is amazing as a person, not just as a performer."
This is terribly sad. We feel awful for Adele and we do really hope she is capable of having a relationship with her dad today, despite what either of them say.
