Norma Jeane Mortenson thus became Marilyn Monroe. Her mom born in #piedrasnegras Gladys Pearl and Marion grew up speaking English and Spanish, fully assimilated into the Mexican norteño life along the border. Gladys Pearl was Marilyn Monroe's mother. Despite demands from studio executives, Marilyn Monroe, discreetly, embraced her Mexican heritage, which she kept secret from the public. @marilynmonroe 🇲🇽 #marilynmonroe #mexicanheritage
