We know filming for Grey's Anatomy is officially underway because Shonda Rhimes herself Tweeted as much. She posted this picture of the lovely Sara Ramirez to prove it!

Shonda also Twittered props to the show's Emmy nominees and said that when Meredith and Derek scenes begin filming, maybe she'll post a picture of it for us! Woo hoo!
