Stevie Nicks mourns Fleetwood Mac's Christine McVie: My 'best friend in the whole world'

A broad range of rockers took to social media to express their sorrow over the death of Christine McVie, co-singer, keyboardist and critical songwriter of Fleetwood Mac.

The 79-year-old “passed away peacefully at (the) hospital following a short illness," according to a statement posted to the singer's Facebook page on Wednesday.

McVie's bandmate Stevie Nicks posted photos of a handwritten tribute in which she called McVie her "best friend in the whole world since the first day of 1975," when Nicks and guitarist Lindsey Buckingham joined the long-running British rock group.

Founding member Mick Fleetwood wrote that part of his heart "has flown away today, I will miss everything about you Christine McVie."

The members of the Eagles released a statement saying McVie was a "vibrant, soulful spirit, and her music was, and will remain, a gift to the world. We had the utmost admiration and respect for Christine."
