The model and former Celebrity Big Brother housemate - whose mum is Angie Best - got a very positive reaction on Twitter after his honest, thought-provoking and informative talk about living with an alcoholic parent.
"Time does fly and people say time heals but I think it just accommodates, as such. When you lose somebody you always forgive. I think. I struggle sometimes to think what was it that made him not be there as a father, but I understand from learning about the illness and the addiction that I have to forgive him," he said.
"As I get older and more comfortable in my own skin, I start to understand maybe why he chose alcohol over me. I know he wanted to be a good dad but I think what happened with my dad, and maybe others in the public eye, is that he had such enjoyment on the pitch but when that joy goes, where does he turn to find that buzz?
"I think he turned to drink, and started quite casually, which led into more and more which led into an illness. So by the time I tried to get to know him when I was about 19 years old, that illness had completely taken over him and my dad wasn't really there any more."
"For years I have been in a shadow, I'm very blessed with it and very proud to be my dad's son without a doubt, but there is a case of when is it Calum Best? What else can I talk about? I have so much going on in my life but for me to explain where I'm going in the future I have to explain my past"
Calum also spoke about his work with Nacoa, the National Association for Children of Alcoholics, of which he is a patron. Founded in 1990, the charity aims to address the needs of children growing up in families where one or both parents suffer from alcoholism or a similar addiction problem.
After the interview, many viewers took to Twitter to praise Calum on the interview, particularly how he spoke about his late father, and brought an important subject and charity to a wider audience.
