Disco legend Donna Summer died Thursday morning at the age of 63, TMZ reports. The five-time Grammy winner had been battling cancer, according to the site.
Summer, who became known as the Queen of Disco, began her career as a backup singer for the trio Three Dog Night. She rose to fame in '70s and defined the sound of the decade after launching her solo career with such hit singles as "Last Dance," "Hot Stuff" and "Bad Girls."

The singer/songwriter strayed from disco in the '80s and developed a more soulful, rock 'n' roll sound. "She Works Hard for the Money," released in 1983, became her biggest hit of the decade.
Over her career, Summer released 17 studio albums and charted 14 Billboard top 10 singles, four of which hit No. 1. Her most recent album, Crayons, was released in 2008. According to TMZ, Summer was working on an album at the time of her death.
Summer is survived by her husband of 32 years, Bruce Sudano of the '70s music group Brooklyn Dreams, and their two daughters, Brooklyn and Amanda.
