Ever since James Corden took over The Late Late Show he has been doing some pretty fun bits. For instance, he does a riff-off with none other than Pitch Perfect's Anna Kendrick.

For those of you who don't know, Anna Kendrick and James Corden were both in Into the Woods, a movie musical that was just in theaters this last Christmas.

Anyway, they took their singing skills and decided to battle it out. Riff-off style. Fans of Pitch Perfect know how this works. And if you're not a fan then I just can't help you.

They were accompanied by The Filharmonic, an acapella group that was featured on The Sing Off and they make a brief appearance in Pitch Perfect 2.

Let the battle begin.

I love how Anna just calls him out! I really think Anna and I could be good friends. We could like hang out and eat popcorn and binge watch Law & Order: SVU. Whoa, side tracked there for a second.

Although, I gotta give some brownie points to James Corden for doing an N Sync song. Kudos, my brother.
