“The Late Late Show” was basically a college a cappella concert Friday night.

Anna Kendrick joined host James Corden in a “Pitch Perfect”-style riff-off to determine who had the best a cappella chops. Along with a cappella group The Filharmonic, the two sang hits including *NSYNC’s “Bye, Bye, Bye “and Pat Benatar’s “Love Is A Battlefield.” Kendrick took home the title, but with those ace song choices and Kendrick and Corden’s fun dance vibes, isn’t everyone a winner? (Not to mention it was an “Into the Woods” reunion.)

Later in the show, Corden sat down with Kendrick and her “Pitch Perfect” co-stars Brittany Snow and Hailee Steinfeld.
