Because Glee loves leaking spoilers all over the internet, here's a video of Gwyneth covering Cee-Lo's "Forget You" and doing the robot.
You can also listen to Gwynnie sing a mashup of "Umbrella" and "Singin' In The Rain" here.
As you may recall, the Goop mistress first warbled on screen in the movie Duets, and sang "Cruisin'" with Huey Lewis. How far we've come!
