In 2010, Alan Jackson and his family received the news no one ever wants to hear. His wife, Denise Jackson, had been diagnosed with cancer. In an episode of GAC's 'Backstory' last year, the 'Chattahoochee' singer confessed what a difficult time it was for him to see his high school sweetheart suffering, saying, "To see her go through that, it was the hardest thing I've ever been through. I've been taking care of her since she was 16, but I couldn't do anything to help her. It was tough."
