"When we did discover that Freddie had this terrible AIDS virus in his body, there was still a disbelief in us," Mercury's bandmate and Queen guitarist Brian May said. "And right up to the last minute, we knew, but we didn't know. We sort of refused to know, if you like."

The famed The Jerry Springer Show host died on April 27, at age 59, at his home in Chicago. A representative for his family, Jene Galvin, told TMZ that Springer had been sick for months, but no one knew how dire his pancreatic cancer was until he was already close to his deathbed.
Galvin added that Springer had always been a fairly private person, and he and his family kept his illness secret as they did not want to worry other people.
The 70-year-old star penned a message to his fans and followers, which his family posted on Instagram after his death, and apologized for not going public about his six-year battle with cancer.
"I have always felt a huge amount of love and respect from my friends, fans and supporters," Reubens continued. "I have loved you all so much and enjoyed making art for you."

Business celebrity and late Apple CEO Steve Jobs managed to keep his secret battle away from the spotlight.
Jobs died on October 5, 2011, months after he stepped down as the chief executive of the technology giant because he could "no longer meet (his) duties and expectations."
The Wall Street Journal noted that the business mogul struggled with several health issues for years, but he kept his rare form of pancreatic cancer diagnosis for nine months after learning about it in October 2003. Jobs reportedly informed a few confidantes about it as he tried to seek treatments for the disease.
"Thankfully we were able to shoot with him not just before he was sick but after, so it could be something we could discuss and listen to him about," the actress continued. "I know that was very important for us and I think it was something that was important to him, too — not to be hiding that from us anymore."
