Glee introduced viewers to Darren Criss this week, while also giving us more insight than ever before into Coach Beiste. It was a frustrating episode in many ways, as outlined by our critic HERE.
But any irritation with the latest installment has already given way to excitement over next Tuesday's episode. How come? Because Gwyneth Paltrow guest stars as a teacher that takes over New Directions while Will is home sick.
Aptly titled "The Substitute," the episode will feature this actress singing in the rain to a Rihanna classic. Get a sneak peek at that performance via our Glee photo gallery and check out the official promo now:
