Earlier today, this TV Addict posted our list of five guest stars that we’re really excited for. Well, thanks to some just obtained photos, we’re going to have to amend that list to include a sixth: Christine Baranski. Who, much to Sheldon (and our) delight will be dropping in on the gang on the December 14th very special Christmas episode of THE BIG BANG THEORY. How do Leonard and Penny feel about this? Take a guess, see for yourself by checking out some more first look photos after the jump.
