Lip Sync Battle: Rachel Bloom performs Teenage Dream

Katy Perry’s “Teenage Dream” is all about feeling that youthful lust. Rachel Bloom’s rendition of the pop song is all about feeling like… an actual teenager — zits and all.

In a sneak peek from Lip Sync Battle, the Crazy Ex-Girlfriend star dons a marching band uniform, pigtails, and the aforementioned blemishes as she mouths along to Perry’s hit. She’s competing against Michael Shannon in the battle, which airs Thursday at 8 p.m. ET on Spike. Get a glimpse of her performance above.
