Demi Lovato And Selena Gomez Give Us A Great Big Dose Of Friendship With This Pic

Delena forever.

Selena Gomez and Demi Lovato are bringing their friendship back in full force.

The two singers grew up together -- first on "Barney" and then as Disney Channel stars. But in the past few years, their friendship remained a mystery, despite being really close in their Mouse House days. In August, we got a glimpse of their reunion when Demi followed Selena on Instagram. On Demi's birthday (Aug. 20), Sel tweeted her well wishes, and soon enough, Demi reciprocated the love. They're back!

And then on Thursday (Sept. 10), Delena launched a super-cute selfie into the world, right after Gomez released her new song "Same Old Love."

"Look at how #coolforthesummer we are.. Friends for years, #sameoldlove," Demi wrote, turning their song titles into hashtags. It looks like Sel and Demi are back for good.

Now one last thing -- sure, they may be #CoolForTheSummer... but are they still #OneAndTheSame?
