Beyonce Knowles' performance in Dream Girls was unforgettable, but we'd just as soon not remember how she got into shape to play her character Deena. In an interview with Oprah she reported using the Master Cleanse—a liquid diet many health professionals have deemed "dangerous" due to its extremely low-calorie intake—to drop 20 pounds in three weeks. "Normally they'd change your makeup or your clothes, but I wanted to go the extra mile," she said.
Admitting to feeling very "cranky" on the cleanse, the singer said she quickly put the weight back on when filming finished. Perhaps this acting job was an opportunity she just couldn't miss but crash dieting for any reason seems risky, especially when she's so fabulous as is!
