If you've never heard Hailee Steinfeld's singing voice, you're in for a treat! The actress posted an acoustic version of the song "Flashlight," which she performs in Pitch Perfect 2 — and it sounds so incredible stripped-down. (Fall Out Boy's Pete Wentz even accompanies her on the guitar.)

Her bestie Camila Cabello tweeted that she was so proud of her friend's video, and we can totally see why!

Of course, now we're wondering if the "magical" thing the 5H singer is teasing has to do with an album. Earlier this year, Hailee was spotted in the studio with Austin Mahone, so her singing career is definitely thriving. We didn't know she had pipes like this!
