Did Halsey Just Tease a New Chainsmokers Collaboration?

If you follow Halsey on Snapchat, you probably saw something a little unusual yesterday. Okay, we can't say it's totally unusual: in her story, Hal is caught singing in the back of a car, clutching a smoothie...but it's what she's rocking out to that made us pause for a minute.

She's singing over the sound of her own voice, one the Internet seems to believe is an upcoming collaboration with The Chainsmokers. Halsey and The Chainsmokers performed the song, "Closer," together at Bonnaroo in early June. Check it out in the Tweet above.
