Rachel Bloom is a total teenage dream!
The Crazy Ex-Girlfriend star channels her inner high-schooler in a sneak peek of this week’s Lip Sync Battle in an epic cover of Katy Perry’s hit, “Teenage Dream,” and frankly, she’s very good at the lip-sync thing.
Donning a marching band outfit, the 29-year-old actress embraces her teenage self -- zits and all! -- performing the catchy tune to the delight of co-hosts LL Cool J and Chrissy Teigen.
No word yet on what song Bloom’s competitor, actor Michael Shannon, will be performing, but he sure has his work cut out for him.
This isn’t the first time “Teenage Dream” has been used on the show. Back in 2013, John Krasinski performed the song in one of the first segments of Lip Sync Battle when Fallon was still hosting Late Night.
Lip Sync Battle airs Thursdays at 10 p.m. ET/PT on Spike.
Earlier this year, Christina Aguilera crashed Hayden Panettiere's amazing Lip Sync Battle performance. Watch the video below.
