Demi & Selena's Best Bestie Pics

If there is one universal truth in this cold, cold world, it is that Demi Lovato and Selena Gomez will be best friends until the end of time. The celeb besties, who have been friends ever since they met as kids on Barney & Friends, have endured enough rough patches and difficult moments to permanently break any friendship — and yet, their bond is stronger than ever.

After a public falling out in 2014 ("I think it's just one of those things where people change and people grow apart," Lovato said on Watch What Happens Live after she unfollowed Gomez on Twitter), the singers-actresses basically said "eff that," resolved their differences, and are now once again making both of their fan bases and the entire Internet green with envy by being the sweetest pair of besties imaginable. (I mean, #FriendshipGoals to the max, seriously.)

2015 is the year of Delena, and the proof is in the super sweet Lovato/Gomez selfie that the "Cool for the Summer" singer posted on Instagram on Thursday. This picture for sure sent fans into a frenzy, now that their favorite pair of celeb best friends has once again reunited like the #forever #nomatterwhat besties that they are. Check out some more pics below that show just how solid Lovato and Gomez's friendship really is.
