The doctors say it dates back to a film where I had these huge prosthetic breasts because my character was breast-feeding. The weight of them, and of the baby, did my back in.
And the most important thing - apart from telling a good, believable story, and being a true character - is to be someone the audience will care about, even if you're playing a murderer or rapist.
I also like the fact that the character isn't a typical footballer's wife, she doesn't need the bling and being at the forefront of everything.
