Do us a favor: Sing “The Barney Song.” Come on, you know it. I love you, you love me, we’re a happy family...Coming back to you? Good because they’re words to live by if you’re Demi Lovato and Selena Gomez.

The two ladies go waaaaay back as in back to the days before they were internationally famous and just two cute pigtailed co-stars on The Barney Show. (Video proof is available and it’s also darn adorable.)

Hanging out with the big purple dinosaur has got to be a life-changing experience and clearly cemented the bond between Dems and Selena. It’s been more than a decade since the two donned water wingies together and their friendship is as strong as ever!

“It's just the evidence of forever. No matter what @ddlovato,” Selena captioned a new photo of her and Dems side-hugging and making kissy faces. Demi then retweeted the pic and added “Love you SO much.. #14yrsStrong.”

Selena probably met up with her gal pal recently thanks to her scheduled X Factor performance. Demi is, of course, a judge on the show. Unfortunately for X Factor fans, however, Selena got rescheduled because of a tech glitch that required the show’s contestants re-perform during the Thursday night episode.

A silver lining? The cancellation meant more time for Selena and Demi to catch up!
