Beyonce Knowles used the Master Cleanse aka Lemonade Cleanse to shed off twenty pounds to portray her role as Deena Jones, a slim back-up singer of Diana Ross in the hit movie, “Dreamgirls.”

Her role required shooting Deena at the age of 16 since the movie follows her life from a young ordinary girl who rise to stardom until reaching the age of 36. So that requires a varying age range not only for her role but for her physical appearance as well.

It was the drive “to go the extra mile” that gave her the urge to go through the diet, and do it faithfully and patiently. And yes, it was all worth it she says.
