Miller is a lesbian. Miller trained at the Guildford School of Acting, from which she graduated in 2004. She has one daughter. Miller is known for her shaved head, and when asked about it, she said: "I used to hide behind my hair all the time. I had this long, relaxed hair, and I was thinking, 'What am I trying to say? What is that about?' It sort of was a lightbulb moment, and I said: 'You know what? I'm gonna cut it off. I'ma start from ground zero and grow an afro.' I was sitting in the barber shop, and he cut my hair and I fell in love with my skull... and I never turned back. And actually, it's afforded me to be able to play a diverse range of roles – it had totally the opposite effect that I feared. Where I thought I'd be very limited to what I'd be seen for, it's done the opposite. So this was borne out of an integrity of loving the self and not having to hide, and loving the fact that I'm an African."
