A source tells ET that Naya Rivera’s ex-husband, Ryan Dorsey, and younger sister, Nickayla Rivera, have moved in together to care for her 5-year-old son, Josey Dorsey. Although Dorsey and Rivera are not romantically-involved, they are committed to raising Josey in the most stable and consistent way possible. Nickayla seemingly responded to critics on her Instagram story on Monday, writing that she is not concerned with how things look because ‘no one can see each agonizing moment we all endure.’
