She has short brown / black hair. She's pretty in a natural kind of way. She is fiesty and moody, kind of an intimidating character. I cannot put my finger on it!
She kind of resembles the girl Ewan McGregor shags in Trainspotting. Kelly McDonald? But it's not her. Not the woman trying to have an affair with Alan Rickman in Love Actually either. She is possibly Irish.
I can't remember if she was in a film or TV series but I'm sure she was British.
