Adele's father has died aged 57.
Mark Evans, the estranged father of the 'Hello' hitmaker, has passed away after a battle with cancer.
A source told The Sun newspaper: "Mark's family are of course very upset by his passing. He always hoped things would work out with Adele, but it remained acrimonious to the end. He made a few attempts to make things right, but clearly it had been too long."
The 33-year-old singer has spoken of her fractured relationship with her father several times in the past, after Mark walked out on Adele's mother, Penny, when the singer was just three years old.
Adele previously admitted she didn't "hate" her father, but their relationship deteriorated further as her stardom grew.
In 2013, Mark revealed he was battle bowel cancer and feared he would never meet his grandson, 8-year-old Angelo, whom Adele has with her ex-husband Simon Konecki.
However, the singer's father claimed in 2015 that her album, '25', had proved to be a cathartic period in their relationship and that they had patched up their dispute.
Mark even called the feud a "misunderstanding", but those claims were countered by Adele in a speech at the 2017 Grammy Awards, in which she told her manager that she loved him "like I would love my dad".
She said: "Thank you to my manager because the comeback, as it were, was completely masterminded by him.
"And you executed it incredibly, and I owe you everything.
"We've been together for ten years, and I love you like you're my dad. I love you so, so much.
"I don't love my dad, that's the thing. That doesn't mean a lot. I love you like I would love my dad."
The 'Rolling in the Deep' singer – who divorced Konecki in 2019 – also failed to mention her father when she picked up the Album of the Year award at the same ceremony.
She added: "Grammys, I appreciate it, the Academy, I love you, my manager, my husband and my son - you're the only reason I do it."
