The family's statement said "we would like everyone to keep Christine in their hearts and remember the life of an incredible human being, and revered musician who was loved universally".Born Christine Perfect, McVie married Fleetwood Mac bassist John McVie, and joined the group in 1971.Their 1977 album Rumours - inspired by the break-ups of the McVies and the band's other couple, Lindsey Buckingham and Stevie Nicks - became one of the biggest selling of all time, with more than 40 million copies sold worldwide.In a post on Instagram, Stevie Nicks wrote: "A few hours ago I was told that my best friend in the whole world since the first day of 1975, had passed away.Few people could have written and sung lyrics so seemingly soppy as "I love you, I love you, I love you like never before", as she did on the classic Songbird, and sounded like they meant them so deeply."
