Some of the choirs members attended Grandes May 22 concert.

So it is going to be really difficult for them to do.

They are amazing though.

Everyone in the choir.

I cant stress how proud we all are of them because theyve just been so professional the whole time.

They got together and they just wanted to do something.

The choir sang Grandes My Everything before the singer came onstage to join in.

After the song concluded, Grande embraced her in a hug.

Tonight is all about love, am I right?

she addressed the crowd after the choir left the stage.

Come on, lets go, she continued, visibly fighting back tears.

Grandemade her entrance earlier during the showwhen she performed Be Alright and Break Free.

She also sang Better Days with Victoria Monet and Where Is the Love?

with the Black Eyed Peas.
