Darren Criss's character serenades Chris Colfer's Kurt on the Thursday episode of Glee, called "The Breakup."

It's not clear which Glee couple is breaking up, though Criss's Blaine is near tears as he sings the Katy Perry hit "Teenage Dream" to his boyfriend Kurt. Criss made his first memorable appearance on Glee singing a rolicking rendition of "Dream." Watch the new performance below.
