The performers took their critics to task following their surprise collaboration on stage last weekend.

Ariana Grande is standing up for Justin Bieber and their Coachella collaboration in the wake of the "Sorry" singer getting heat for using a backing vocal track during their performance.

Bieber joined Grande during her closing set at Coachella last weekend, taking the stage for the first time in years. While his appearance made headlines, some critics chastised the singer for supposedly lip-syncing.

Grande took to Twitter to slam the haters, and explained that his participation was something that only came together minutes before her set began.

"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," she tweeted in response to posts Bieber wrote, taking his own critics to task.

"People are bored. people don’t know how it feels to be under such scrutiny," she continued. "The world was happy to have u on stage again."

"Circling back. your fans, friends&the world is thrilled to have you back. everyone was so happy to see u smile like that," she added. "No one will ever understand how it feels to be u, but it’s not their job to. take care. make music. u are loved. p.s. everyone in that video will b streaming."

Grande concluded, "[I] don’t like when people try to ruin beautiful moments for my friends that’s all. have a good day."

Grande's posts come in response to a lengthy message Bieber wrote calling out E! News Host Morgan Stewart, who mocked the singer for using as backing track.

"@Morgan_Stewart 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," wrote Bieber, who has been very public and vocal about his own mental health struggles in recent years. "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 backtrack like most cameos do this is a normal thing," he continued. "And rather than try and make people feel accepted and loved you find things to pick apart like the world isn’t full of that already.. we can find something negative to say about anything or anyone. When are we gonna be the kind of people that find joy in adding value to one another and not tearing each other apart.."
