She ,& her sister Serena, actually grew up in Compton California which is actually quite close to Bellflower almost adjacent to Bellflower although a little bit different socio-economically,but not so much, so I think it's fair to call her a Bellflower native just like if she was from Downey or Artesia or Cerritos ie the greater ABC area
