Selena Gomez and Demi Lovato have had a rocky friendship – to say the least. Their relationship dates all the way back to the Barney days and continues on throughout their Disney Channel era. But lots of factors caused these two to grow apart. Some of it was just life, there were even rumors that Justin Bieber had come between them.

To be honest, we'll probably never get the real story. But, it seems like Demi just called out her former best friend on social media and fans of Delena are going wild over it. Unfortunately, they aren't actually together but Demi clearly referenced Selena and one of her most popular songs.

Demi shared a photo on Instagram hanging out with a few friends and wrote, "Kill em with kindness…. or choke em with a smile on your face. ?."

Yasss, Delena is here! There is one thing we should all remember, though. The phrase 'Kill em with kindness' has been around long before Selena used it as the title of her song. So, it's possible that Demi wasn't even thinking about Selena when she crafted the caption. But, that's no fun and we're hoping that's not the case. Because whether Demi realized it or not, she just gave Selena the sneakiest shout out ever. Delena shippers are literally living over it!

Selena and Demi haven't been seen together in years. However, Demi actually posted a photo with Sel back in September of 2015. She captioned that pic, "Look at how #coolforthesummer we are.. Friends for years, #sameoldlove ???."

Of course, everyone was super confused but super excited at the same time considering their friendship was considered to be on the outs. These two obviously have their own lives and are doing their own thing so hanging out together is probably not the first thing on their minds. But, after all of these clues, it's safe to assume that there's no bad blood between the girls.

There's a whole lot of history and Barney always brings people together.
