0517_donna_singleDonna Summer, AKA "The Queen of Disco," died this morning after a battle with cancer.

According to TMZ, the 63-year-old singer was in Florida at the time of her death.

Summer hit it big in the '70s with classic disco hits like "Last Dance," "On the Radio," "Hot Stuff" and "Bad Girls."

The five-time Grammy Award winner married Brooklyn Dreams singer Bruce Sudano back in 1980. They had two daughters together.

Sources tell TMZ Summer was trying to keep the severity of her illness under wraps -- and she "didn't seem too bad" just a few weeks ago.
