Selena Gomez and the Jenner sisters were totes BFFs for a while and there were even rumors that Selena had hired Kris Jenner to manage her career after she fired her own parents.
It looks as though the friendship has come to an abrupt end, however, as Selena sent the Jenners the ultimate social media f-you over the weekend:
She unfollowed both of them on Instagram! The horror.
To make her message perfectly clear, Selena then deleted the dozens of selfies she'd taken with the sisters. Burn. In teenage girl world, that's basically the equivalent of throwing a brick through someone's window.
Some have suggested that Selena might simply be cleaning up her friends list before deleting her Instagram altogether, but knowing how sensitive the Kardashian-Jenner clan can be - we're guessing Kendall and Kylie didn't take it that way.
If there is some beef between the trio of young stars, it developed recently. Just last week, Selena was spotted hanging out with the Jenners at Coachella (when she wasn't busy holding hands with Justin Bieber).
There are those who believe Selena never had much in common with the inappropriate selfie queens and was simply using her new girlfriends as some sort of bizarre attempt to make Taylor Swift jealous after the friendship between the two singers soured.
More on this totes ratchet drama as the story develops.
