Wait, When Did Halsey And Panic!'s Brendon Urie Become Best Friends?

And when do we get to hear their collab?

Yesterday (April 12), Brendon Urie of Panic! at the Disco celebrated his 29th birthday, and his new pal Halsey honored the occasion with a very cute pic of the two together.

“Happy birthday to one of the most important people in my life,” wrote Halsey on Twitter, where she’s now active again after a brief hiatus.

The two musicians met back in November, when Urie was blown away by one of Halsey’s live shows. Sometime between then and now, they must have bonded in a major way.

Before you take that rose emoji as a sign to start shipping, though, please note that Urie’s wife Sarah also wished him a happy birthday via Instagram.

Halsey’s just a friend, but we wouldn’t exactly object if the pair put their heads together on some new music.
