British singer Rochelle Wiseman has blamed her fluctuating weight on the side effects of an ovarian cyst.
The Saturdays star spoke out last year (10) after gossips taunted her about her expanding waistline, insisting she was simply "human and curvy".
But now she's revealed the condition caused her to pile on the pounds before she underwent surgery to have the cyst removed.
Wiseman tells New! magazine, "I had an operation at the start of last year. I had a cyst on my ovary and it made me put on a lot of weight. I went a full dress size bigger - from a size (U.K.) 8 up to a 10, maybe even a 12. Everyone thinks I've tried to lose weight, but I genuinely haven't."
