Graham admits her mum and dad had no idea what to expect from her role as Rollergirl in the film - and were so shocked they severed contact with her.
She says, "They didn't really want to hear my point of view, and thought that, because I took the part, then I was like that in real life.
"It would be nice if I did have a good relationship with my family, and yes, part of me longs to have a mum and dad who love and accept me for who I am. But if they never do, it's OK."
