Ariana Grande invited Justin Bieber on stage during her last Coachella set and while it was a beloved moment for fans, Nightly Pop host Morgan Stewart had something else to say. “I did not realize it was going to be that bad.” Morgan said on her show, adding how Justin "definitely looks like he put an oxy pad on that forehead, but I don’t care. That is fucked up!”

Morgan's comments came back to bite her after Justin called her out on Twitter. "Just saw a video of you ripping me to shreds saying I was lip-syncing. They played the song and i just sang overtop of it.. regardless why spend your time tearing people down. It’s People like you that are bullies at school that are making kids suicidal," he tweeted.

The "Sorry" singer continued: "Imagine if you spent even half the time you spend laughing at other peoples expense actually building people up and encouraging people how much positivity you could bring. What hurts about this is the fact that you have a platform to make a difference."

Ariana chipped in, explaining how Justin's set was a surprise. "We also decided to do this ten minutes before my set started. we had 0 soundcheck, 0 rehearsal. u were singing with the back tracking like most cameos do. people are bored. people don’t know how it feels to be under such scrutiny. the world was happy to have u on stage again."
