The latest dose of shade was served by Selena as she has changed her Instagram DP from a pic of her mother as an homage to a pic of herself from her "Wolves" music video.
And that's not all!
An eagle-eyed fan also noticed that Sel got her girl squad to unfollow Mandy on Insta just weeks after the mother daughter duo unfollowed each other.
Things are getting so intense between these two that we wonder if they'll ever be able to patch things up again.
We certainly hope so...
