Gwyneth Paltrow was back in Holly Holliday mode last night to take the stage with the Glee cast members in East Rutherford, NJ! The actress, who was in NYC earlier this week for the Bent on Learning benefit, looked right at home in her costume and she sang and danced with the kids to Cee Lo Green's "Forget You." The song was apparently being recorded for the Glee Live! 3D! tour movie coming out in August — check out Gwyneth's latest performance!
