The singer revealed her dramatic weight loss came after doctors ordered her to get fit when they discovered she had a heart murmur. She shed 19lbs and dropped from a size 12 to an eight in six weeks.
She told a magazine: "I make sure I work out three times a week now, and I don't hold back. It's a hardcore routine and I'm usually in the gym for at least an hour-and-a-half. I just like being more toned, it has made me really happy and I know I will never be super skinny because I would never be happy."
