Matthew Rhys wants confidence in a woman

"[A woman should] just come right up and introduce herself ... in the supermarket, at the car wash ... Bring it on!" he says of his "sadly single" status.

He also reveals to the magazine that his dream girl was Audrey Hepburn. "She seemed to have this sense of unapologetic certainty about who she was and no matter how cute she was, she wasn't going to take any shit from anyone," he says. "Very appealing."
