(CNN) — A Taylor Swift fan died Friday night before an “Eras Tour” show in Rio de Janeiro, Brazil, the singer said on Instagram Stories.

“I can’t believe I’m writing these words but it is with a shattered heart that I say we lost a fan earlier tonight before my show,” Swift said. “I can’t even tell you how devastated I am by this. There’s very little information I have other than the fact that she was so incredibly beautiful and far too young.”
