The Pitch Perfect 2 actress, who was nominated for an Academy Award for her star turn in the Coen Brothers' 2010 film True Grit, recently signed with Republic Records and is working on her debut album.
It's a surprising development that even she didn't see coming.
Earlier this month, she told Jimmy Kimmel she didn't think of herself as a singer until joining the cast of Pitch Perfect 2 and sang live for the first time on the movie's set.
However, as luck would have it, she's a natural.
To prove it, she uploaded a video of herself singing a lovely, acoustic cover of Jessie J's Pitch Perfect single "Flashlight" to her YouTube channel.
Watch the stripped-down performance now and keep your eyes out for an all-star cameo at the end.
