Something seems to take over your body every time a Panic! At The Disco song comes on. It causes every nerve in our body to come alive as we scream about closing a damn door. So when the timeless P!ATD jam came on at Halsey reacted just like the rest of us would.

Our little emo hearts are so full.

Last night marked another iconic Halsey Presents annual Halloween party, an invite-only event that has fans on the edge of their seats waiting for Halsey to unveil her always-on-point costumes. This year's theme was "Villains of Gotham City"—and the night did NOT disappoint.

Donning an incredible Poison Ivy costume, our Queen recreated the iconic pink gorilla entrance to the botanical garden party performed by the villainess in the Batman and Robin movie.

And of course, she nailed it.

The incredible Alison Wonderland did a set at the party, and when she dropped Panic's "I Write Sins Not Tragedies," Halsey THRIVED.

Honestly, same.

And the best part? It was all for a good cause.

Our girl didn't stop there either. Check out her performance of her latest track "Without Me" below!

We love legends supporting legends, and this isn't the first Halsey/Panic! At The Disco moment that has warmed our little emo hearts.

From Brendon Urie gushing over performing with her at Coachella to Halsey asking Brendon to explain a famous Panic! lyric, we're LIVING for this friendship.

So when are we getting that collab?
