Late on Friday we got to see Darren Criss (Blaine) serenade Chris Colfer (Kurt) with "Teenage Dream" in a clip from this week's special edition of Glee. But what does "Teenage Dream" singer (and the new Mrs. Russell Brand) think about the cover?

"Oh...My...Gosh... this just brought a sweet tear to my eye!" Katy wrote on Twitter. "Teenage Dream on GLEE makes my heart go WEEEEE!" Oh, Katy. Always with the rhyming. The good news is that it makes our hearts go wild as well. We can't wait to see more of Darren and Chris as the season goes on!
