The temperature got hot, hot, hot when The Chainsmokers took the VMA stage with Halsey Sunday night (August 28) at Madison Square Garden. They performed "Closer," currently the top song in the country. And they obviously took that title literally, because they really couldn't keep their hands off each other.

It all started with this come-hither look, which sent sparks flying across the stage:

Then Andrew Taggart, one half of the EDM duo, snuggled up to Halsey as the duet continued. He was this close to that underboob action! 😳

And he went lower...

And lower...

Then came more onstage cuddles, because PDA is totally acceptable at the VMAs.

🎶 So baby, pull me closer in the back seat of your Rover / That I know you can't afford / Bite that tattoo on your shoulder / Pull the sheets right off the corner of that mattress that you stole / From your roommate back in Boulder / We ain't ever getting older 🎶

Halsey has a shoulder tattoo of a rose. Just sayin'.
