Ariana Grande has another big surprise, and it involves The Hunger Games! In a livestream last night, the singer revealed that she is the unnamed artist listed on the Mockingjay soundtrack.

Lorde teased that the song wasn't listed because it's still a work in progress, so we still don't have any details about the mysterious "Track 5."

The "Problem" singer has been hard at work on her new music video, so we can't even believe that she time to make another song. Since we have to wait to even see what it's called, it must be good!
