Edit: Look: http://www.tv.com/people/katie-mcgrath/trivia/ Search the page for "blonde" or scroll down the sub-title "Personal". I think this is official stuff. Katie isn't a completely MAINSTREAM celeb people obsess about so much of her personal stuff isn't scattered all around the web. But I am a little surprised her hair is mentioned to be naturally blonde less than it is.
