The crazy-busy singer recently lamented her weight loss in a chat with Us Weekly, saying, "I'm a size 0 — and not happy about it! I went way too far. I prefer myself a bit chunkier. I want my old butt back!"
The chart-topping singer claims her out-of-control schedule is to blame for her new physique, and we believe her. Between her burgeoning movie career, her upcoming seventh album, and all the appearances that come with being a megastar, RiRi is one in-demand lady. Her fast-paced life apparently caught up with her the night of the 2012 MET Gala, when she was hospitalized for flu-like symptoms.
