Normally I'm not one to post too many Glee spoilers, but this one is just too good to pass up. We've been waiting for Gwyneth Paltrow's guest appearance for months, and here's a sneak peek at the actress belting it out with the gleeks. She puts a feminine spin on Cee-Lo's "Forget You," and whether or not you were feeling Gwyneth's live performance at the CMAs, this clip is still worth watching (she does the robot!). We're officially excited for it to air in the UK, but how do you feel about your first look at Gwyneth as the new substitute teacher for the glee club?
