WATCH: Fil-Am acapella group backs up Anna Kendrick in 'Pitch Perfect' riff-off

After hearing that host "Late Late Show" host James Corden has been telling people that he's the best acapella singer in town, "Pitch Perfect" star Anna Kendrick challenged him to a riff off.

She was backed up by no less than The Filharmonics, one of the most popular acapella groups in the world.

The Filharmonics, consisting of Filipino-American members VJ Rosales, Joe Caigoy, Trace Gaynor, Barry Fortgang, Jules Cruz, and Niko Del Rey, also appear in the "Pitch Perfect 2" as Manila Envy, one of the groups competing against Kendrick's group Barden Bellas.
