From an article I got in a Google alert:
Harry Styles had a secret friendship with Glenn Frey
APRIL 27, 2017

Harry Styles formed a secret friendship with Eagles star Glenn Frey before his death in 2016. The 23-year-old star grew close to the American singer before he passed away aged 67 in January last year, and Harry even attended his memorial service in Los Angeles alongside the likes of Stevie Wonder and Don Henley. Cameron Crowe, who interviewed Harry for Rolling Stone magazine, told The Sun newspaper: “The first time I met him was for the memorial. He was really missing his friend.” The extent of Harry’s friendship with the star was never previously known, but he did pay tribute to the Eagles singer a day after his death. In a post on Instagram, Harry wrote: “Rest in love and peace, Mr Frey.”
