Mark Evans told The Sun in 2011, "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." The superstar singer was raised predominantly by her mother, Penny Adkins, in London after Evans left them (via The Mirror). The struggling father publicly shared his cancer battle in 2013, bemoaning the fact he'd probably never get to meet grandson Angelo, whom Adele gave birth to the year before, as a result. It's unclear whether the two ever did get to meet, considering the iconic star maintained she didn't reconnect with her father in her adult years. A source advised The Sun, "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." 

They added, "He made a few attempts to make things right, but clearly it had been too long." The relationship allegedly soured further after Evans gave a tell-all tabloid interview, with even Adkins reportedly warning him it wasn't the right move. Adele celebrated her 33^rd birthday earlier this month, writing "Thirty Free" alongside a selection of snapshots on Instagram. Fans are hoping a new album is on the way soon, since the singer typically lines them up with her birthdays. At the time of writing, she has yet to make any public reference to her father's passing.
