Some kind of do-si-do is going on with the grown-ups of Dance Moms.
Miller announced she was quitting the show in an angry Instagram post Monday in which she blasted the show's producers for not giving her the credit she feels she deserves.
After Miller reportedly had been acting erratically on set and gone AWOL for three episodes, Dance Moms brought in choreographer Laurieann Gibson to instruct the young dance students.
Miller is currently awaiting sentencing after pleading guilty to felony bankruptcy fraud.
Dance Moms representatives wouldn't confirm that Burke is replacing Miller, saying that filming on the current season ended last week and Cheryl Burke will appear on future episodes when Miller is unavailable.
