A little over two years since it was released, The Chainsmokers & Halsey’s “Closer” has officially gone diamond in the US, selling 10 million equivalent units.

The Chainsmokers were presented with their plaques by Jimmy Kimmel, on whose show they also performed their new single “Side Effects” with Emily Warren.

The Chainsmokers wrote: “CLOSER is officially DIAMOND in the U.S. !! we could have never imagined having one of our songs going 10x platinum. we wrote this song with  @freddykennett and @shaunfrank in the back of our tour bus 3 years ago thinking it would be fun a record for our friends to jam to, nothing more, congrats boys!”

Halsey, on the other hand, hasn’t been home to open her plaque since she’s been touring so much.

“Been on tour for a hundred years so I haven’t even gotten home yet to unwrap this baby. CLOSER IS CERTIFIED DIAMOND! 10 times platinum! TEN MILLION! In just 2 years. Thank you to every single beautiful little heart that sang this song at the top of their lungs.”
