Justin Bieber was honest about being surprised Ariana Grande called him on stage at Coachella, and not preparing to perform. He got some criticism for that, particularly from E! News’ Nightly Pop show host Morgan Stewart. And Justin called her out.
He tweeted at her to build people up instead of tear them down…
And rather than being positive you belittle people. Think about how awesome it felt for me to be on that stage after being away for so long the excitement and joy it gave me doing the thing i love the most, i sang to to backtrack like most cameos do this is a normal thing,
