The singer, who recently announced the title of her forthcoming LP as Girl on Fire, confessed that breaking free of misconceptions about her was the inspiration behind the set.
She told the Daily Star: "I'm in the studio right now working on my new album and it is called Girl on Fire. That's exactly how I feel.
"Making this record, I felt in some ways like a lion locked in a cage. I felt like a girl misunderstood who no-one really knew."
She continued: "I felt like it was time to stop making excuses for any part of my life that I wanted to change. I became a girl on fire, the lion broke free."
Keys recently admitted that she was "so excited" to release the record, adding: "[It's] about new beginnings, new perspectives and fresh starts."
