fears she's destined for a weight battle as she gets older, insisting her energetic schedule is the only thing keeping her slim.
The singer loves her voluptuous physique, but she's convinced she'll pile on the pounds as she gets older and her metabolism slows down.
The 25-year-old hitmaker explains, "I'm kind of voluptuous and I've always been that way. (But) I'm young and metabolism is on my side and my schedule is so crazy that I lose weight from the intensity of it. But if you ask me that question in five or six years and I'll probably have a different answer for you."
