The disco star was reportedly trying to keep the extent of her cancer illness under wraps while she completed a new album, though sources who saw her several weeks ago said she "didn't seem too bad." On May 17, 2012, Summer died at the age of 63 after a battle with lung cancer and breast cancer. Summer is survived by her husband Bruce Sudano, their daughters Brooklyn and Amanda, as well as her daughter Mimi from her previous marriage.
The five-time Grammy winner was known as the "Queen of Disco" and rose to superstardom in the 1970s with her hits "Last Dance," "Hot Stuff,""Love to Love You Baby" and "Bad Girls". Summer was the first artist to have three consecutive double albums reach number one on the US Billboard chart, and she also charted four number-one singles in the United States within a 13-month period.
