Viola Davis delivered one of the greatest performances of 2020 as blues legend Ma Rainey in Netflix’s Ma Rainey’s Black Bottom. The Oscar-winning actress, 55, revealed she gained some weight in preparation for the role, but turned to Gabriela Mclain to help her get “back in shape” post filming. “Love my amazing trainer, Gabriela Mclain! She played a major role in getting me back in shape after gaining weight to play Ma Rainey,” Viola tweeted on December 17.
