Rick Diamond/Getty Images for CMTAdele's father admits he hasn't always been a great dad,.
But on Sunday, Mark Evans told the Daily Mail he desperately wants to rekindle his relationship with the "Someone Like You" singer and meet his only grandchild.
"I've left messages on her phone, I've written to her and I've sent her birthday and Christmas cards," he said. "But it's like I'm dead to her."
"I'm not interested in her celebrity status or her money," he added. "I just want my daughter back and I want to be a proper granddad to the little one."
By "the little one", he means Adele and boyfriend Simon Konecki's 3-month-old son. Adele was spotted wearing a gold necklace that spelled "Angelo", leading many to speculate that's her son's moniker.
(British tabloids have reported Angelo James Konecki is the child's full name, although Adele has yet to publicly confirm any of this information.)
Her estranged father, however, is not pleased with his grandson's possible name.
"I'd hoped so much that she'd put my late dad's name, John, in there somewhere, but alas it looks as if it is not going to be," he said. "I'm not sure why she's chosen James, other than a reference to James Bond, and God alone knows where Angelo has come from. It's very L.A., isn't it?"
Evans said he laments "missing out on so many of the joys of being a grandfather. Simple pleasures like taking him out for a walk in his buggy along the promenade at Penarth like I used to with Adele, then stop off for an ice cream on the way back."
But as much as Evans says he misses his daughter, he won't be watching her performance of "Skyfall" at the Oscars. "I know she'll win [for best song] because she's brilliant, but I won't be there and I won't even watch it on television," he said. "It would upset me too much to know that I was watching something that my dad never got to see. I'd break down and fall apart."
