The prolific pop musician announced this spring that he had reconciled with his mother after a nearly decade-long estrangement. John shared a smiling photo of the duo on Mother’s Day, writing, “So happy we are back in touch.” John had not spoken to his mother since an explosive fall-out in 2008. Farebrother told the Daily Mail in 2015 that the estrangement was sparked by John’s mother’s refusal to cut off contact with two of his oldest friends, Bob Halley and John Reid, after he ended his relationship with them. Farebrother told the British newspaper, “‘I told him: ‘I’m not about to do that and drop them. Bob is like a son to me. He has always been marvelous to me and he lives nearby and keeps an eye on me.’ ” She added, “Then to my utter amazement, [John] told me he hated me. And he then banged the phone down. Imagine! To me, his mother!” John Olson/The LIFE Picture Collection/Getty Images In 2016, John had confirmed to the Daily Mirror that he had buried the hatchet with his mom, saying, “We are now back in touch.” “Out of respect for my mother’s privacy, I have always shied away from speaking publicly about our relationship,” he added. “However, I can say that we are now back in touch and have been so since my mother’s 90th birthday.” Elton John and his mother Sheila Farebrother.

The pop icon had canceled all of the April and May performances of his Las Vegas residency, The Million Dollar Piano, at The Colosseum at Caesars Palace, due to a “harmful and unusual bacterial infection,” a rep told PEOPLE.
