Summer was in Florida at the time of her death.
The singer was trying to keep the extent of her illness private, but sources say she seemed OK a few weeks ago and was even trying to finish an album she had been working on.
Donna Summer was a five-time Grammy Awards winner who rocketed to fame in the 1970s with classic hits like “Last Dance,” “Hot Stuff,” and “Bad Girls.”
She continued her epic run in the ’80s with “She Works Hard for the Money” and “This Time I Know It’s for Real.”
Summer married Brooklyn Dreams singer Bruce Sudano in 1980 and together they had two daughters.
R.I.P. Donna Summer!
