Girlfriend of the Week

This week's GOTW is actually a mystery.  Well okay, not to me.  I know who she is.  I figured it might be fun to see if you guys could figure it out.

I will give you some hints.

1.  She is an actress (or is the term female actor?)
2.  She will be playing the wife of a certain mead drinking god.
3.  She made an appearance in episode 103 of a certain hilarious comedy show.

So, let us see how well you know your hot chicks.  Good luck!
