They love you."Soon afterward, the hashtag #SelenaEndedJustinParty began trending on Twitter.Most of the tweets included a photo of other celebs sipping tea, or a GIF of Gomez laying down the law.

"And now she's breaking his career, woah."One person even noted this was karma for Bieber shading Gomez's BFF Taylor Swift, tweeting, "Snakes eat RATS." Another user crafted a suggested track list for Bieber's next album, with every song title including the word "Sorry.""She used you?" one user wrote . "But she was famous while you were still in diapers."All the shade fit to print in 140 characters.
