Miller is part of the LGBTQ+ community. In an interview with STYLECASTER she said:
“It’s always a thing to come out. It’s just normal culture, which is why I’m now speaking out about as an older Black female. There are women my age who still don’t, for whatever cultural or family reasons, feel free enough to speak about their sexuality. For the younger generation, they’re not seeing any queer aunties or any gay uncles. That’s one of the reason I’m now kind of going, ‘Fuck it!’ I have nothing to hide. Here I am.”
