Ariana really had a bad experience with her time on the voice as a coach, it was not her time on the show that caused her severe depression after the end of her season, but the comments from her fans and other viewers have contributed to her depression, so you can forget about her coming back, she'll never come back on this show again
how many times does it have to be said that Ariana is *not* returning to this show lmao.
she hasn't toured in 5 years. she recently shared with the Arianators that it will be her priority when she has the time (though Wicked promo makes it tough). she is not going to spend her free time judging on The Voice when she could be touring or promoting her new album💀
when she did S21 she was not promoting an album or releasing music. now, she is currently in the midst of an album cycle and is the #4 most streamed artist in the world.
