Who's that lady... who'd that lady? Lovely ladyyyy... who's that LaDaY? SHE'S MOTHER-EFFING Mary Cassatt and she is not here to play. Ooooo we love a good POWER B and this one can definitely sit with us. We will get into the childhood, the will-they won't they's with another famous impressionist, and we'll get into WHY this girl changed the art world... We love you! The BB's
