The bond between Demi Lovato and Nick Jonas is the sort of connection we hope we have within our own squads. They're extremely loyal to each other, and their most authentic selves when they're together. Like, how beautiful is that?!

She wrote a super sweet message to Nick to celebrate his birthday, and it’s major #SquadGoals.

Their friendship hit a rough spot when Demi grew distant as a result of her mental illness.

In 2010, she had to leave the Jonas Tour before it was over to focus on herself.

We definitely get how important it is to take a step back sometimes, even from the best friendships and relationships, and take time to put all of your energy toward yourself and your mental health.

We’re so happy to see this duo back in action!

And now we're dying to go re-watch their best moments of Carpool Karaoke for the millionth time. Ugh, we love them so much!
