Joe Jonas Had An Entire Crowd Sing 'Happy Birthday' To Demi Lovato

Happy birthday, Demi Lovato. Go eat some cake by an ocean.

For some reason, the fact Joe Jonas and Demi Lovato are still friends is oddly heartwarming. I don't know them personally or will likely ever be in the same room as them, but knowing the famous ex-couple is still on good terms gives me a weird sense of hope.

It's like remembering Dr. X and Magneto were friends. Kinda. OK, it's a stretch but YOU GET IT.

Jonas showed his platonic love for Lovato while in London performing with DNCE over the weekend at V Fest.

He got the crowd at the world famous G-A-Y nightclub to sing "Happy Birthday" to the newly 24-year-old pop star.

He also tweeted some birthday wishes to Demi.

Happiest of incredible birthdays to one of my best friends @ddlovato I'm so glad to have you in my life. Have the best one yet — J O E J O N A S (@joejonas) August 20, 2016

And here is a nice, sweaty, post-show pic of the band I think we all deserve to look at.

Though the G-A-Y nightclub performance wasn't part of the festival, DNCE was in London performing at both V fests this weekend.

They also drank some coffee.

Throughout the weekend they performed at London's Islington Academy and Weston Park.

HBD, Demi. You rock, never change.
