The family of Donna Summer is hitting back at media reports that smoking contributed to the disco diva's death on Thursday.
Summer died of lung cancer, family members said in a statement on Friday. However, they claim that contrary to some reports, the "Hot Stuff" singer was a non-smoker.
"Obviously, numerous factors can be attributed to the cause of cancer in general, but any details regarding the diagnosis and subsequent treatment of Ms. Summer's case remain between her family and team of doctors," the family said in a statement.
Summer was 63 years old and was best known for her hit singles "She Works Hard for the Money," "Bad Girls," and "Last Dance."
Summer's publicist Brian Edwards said in an earlier statement that funeral services for the singer will be private and will only include family and close friends.
She is survived by her husband -- singer and producer Bruce Sudano; their daughters, Brooklyn and Amanda; and Summer's daughter, Mimi, from a previous marriage.
