Sing Along With The 'Pitch Perfect' Bellas As They Pitch-Slap Some Bros

We can't press play just yet on the sweet, sweet a cappella harmonies of "Pitch Perfect" (the movie doesn't hit theaters until October 5), but here's a little prelude to tide you over: a brand new clip from the film, in which our fave girl crushes Anna Kendrick and Rebel Wilson dominate the pants off their musical rivals with an impromptu riff on an R&B favorite by Blackstreet. Do you like the way they work it? (Answer: NO DIGGITY.)

And if seeing the ladies dish out a nice hot helping of a cappwnage has inspired you to start beatboxing, harmonizing, and vocalizing on your own no-instruments arrangement, don't limit your performance to your shower! The movie is breaking out it's own contest in conjunction with "Pitch Perfect" actor and a cappella heavyweight Mike Tompkins, with a chance for talented music geeks to showcase their skills in a new music video. It's an a cappella rendition of "Starships" by Nicki Minaj, and the field is wide open for vocals, dance moves, beatbox, and/or guitar, bass, synth and back-up sounds—the best of which will make their way into an arrangement and music video that'll debut on Mike's YouTube channel and be featured on the "Pitch Perfect" DVD.
