Born and raised in Inverness, Scotland, Karen was an only child. She learned how to play the piano at age 7, and developed a huge love of acting as a child. At age 16 she began studying acting at Telford College in Edinburgh. At 18, she moved to London, and her beauty was soon noticed.
In 2007, Karen began modeling, and took on a few small television roles. Her big break came in 2010 when she was cast as the 11th Doctors companion.
Karen has quickly become a Comic-Con favorite, as well as a favorite of Dr. Who fans. She and Matt Smith are also portrayed in a comic book of the same name published by IDW. With her fabulous looks, and witty personality, this girl has no place to go but up, and that is why I chose her as this week's Hot Nerd.
