RiRi is noticeably skinnier lately, but not by choice exactly. If she had it her way, shed pack on the pounds. Rihanna has literally been running herself ragged because she is just so busy doing movies and working on her seventh cd. She tells us weekly her schedule is crazy, she gets no sleep and its harsh on her body. She says, Im 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.
