"I did not know it was going to be so bad," said Stewart, according to Us Weekly.

Bieber fought back Wednesday to social media about the host in a series of tweets, defending the appearance of his lip sync and reprimanding him for "shooting people."

In his first tweet, Bieber accused him of being a brute, saying: @Morgan_Stewart has just seen a video of you tearing me apart saying that I was synchronizing my lips. They played the song and I just sang it .. no matter why you spend your time demolishing people. It's people like you who are bullies at school who make children suicidal. "

He then continued to challenge his comments, suggesting his time would be better served to "train people". He also reminded her that it was her first performance in 2 years and that he was "singing to backtrack as most cameos do."

"And rather than trying to make people feel accepted and loved, you find things to separate as if the world was not already filled … we can find something negative to say on any matter or whoever, "he said. added in the thread.

The singer "baby" concluded: "When will we be the kind of people who will find joy in giving each other value and not tearing themselves apart?"

I had to resume my rhythm, my booty back, you know what I say? Thank you very much, Coachella. Thank you very much, Ariana Grande. We love you so much, man. Thank you so much."

Bieber last set the stage in July 2017 for his "Purpose" world tour, but suddenly canceled the last 14 shows "after much thought". He told Vogue in February that he had decided to stop shooting because he was "really depressed".
