Sister Bearonce began her career as a back up dancer for a well known (and here unnamed) pop music singing and dance star (who married Jay Z) until she was fired for "conspicuous consumption" backstage at the Superbowl (TM) half time show. 

Resigned to a career in the manufacture of cupcake flavored anal wipes, she leaped at the chance to join the Sisters where she continues the fine tradition of refusing to wash or shower.
