Music legend Donna Summer kept the extent of her illness secret to some of her closest friends, Breaking Celebrity News has exclusively learned.

The five-time Grammy winner, 63, was suffering from lung cancer and passed away at her home in Sarasota County, Florida on Wednesday morning.

The family released a statement to Breaking Celebrity News Thursday confirming the disco diva was "surrounded by her family at the time" she died.

"Early this morning, we lost Donna Summer Sudano, a woman of many gifts, the greatest being her faith. While we grieve her passing, we are at peace celebrating her extraordinary life and her continued legacy. Words truly can't express how much we appreciate your prayers and love for our family at this sensitive time. The Sudano Family."

The Last Dance singer had been battling cancer, but she kept the extent of her illness quiet, her longtime attorney exclusively told Breaking Celebrity News.

“Donna was a very private person, and I suspected there was an issue because she had turned down very lucrative work over the past year, but she never talked to me about being sick and it was never confirmed,” said Gerry Rosenblatt.

“She turned down all the interviews and all scheduled work. You knew that something was up and I suspected a serious illness.”

As the music world mourns the loss of another legend, Rosenblatt told Breaking Celebrity News that he was still in shock over the devastating news.
