Adele's father, Mark Evans, admitted he wasn't there for his daughter but hopes to meet his 10-month old grandson in case he passes away before he gets the chance, reported Sun Online.
"I was not there for my daughter when I should have been. I have regretted that every second of every day. It tears me up inside. I still haven't met Angelo and I'm facing the fact I may never do. It could be over for me before I get to make my peace with Adele," he said.
However, he is still attempting to repair their relationship.
"I'm hitting a brick wall. Trying to get hold of my daughter is like trying to call the US president. All my friends say, 'What's going on Mark?' I have to tell them I just don't know. I've just been ostracised.
"I haven't got Adele or Penny's number. I sent birthday cards via her record label but never hear back.
