Naomi also looked back on how she had dealt with the rejection that came with a career in Hollywood.
She mused: 'I went through a full-blown decade living in Hollywood, of being told, ‘No, no, no.’ It was crushing. And, bit by bit, it really tore me down, to the point that I couldn’t get out of that cycle.
