We are so freaking excited for the nationwide release of Pitch Perfect this Friday. And we have this awesome behind-the-scenes footage with Ester Dean, one of the lead members of the Barden Bellas, the all-female a cappella group in the movie.

Don’t know Ester yet? Well, she’s pretty awesome and big on the song writing scene. She’s written songs for people like Katy Perry, Beyonce, Nicki Minaj, Kelly Clarkson, Rihanna and Lil Wayne. Badass, right?

Pumped to see Pitch Perfect this weekend? Let us know in the comments.
