During her performance, the 25-year-old almost fell during the song's second verse after she had climbed onto a white chair to sing a few lines.
Ariana Grande is rolling out her new era of music with a playful ode to a romantic comedy classic. Holding hands with my mama.
Ariana's dance routine was a tribute to the classic Hollywood film "First Wives Club", however Ari's chair stunt saw her stumble and nearly fall to the ground, as you can see in the video above.
In addition to the trio's ensembles, the stage was outfitted as if for a wedding reception, with tables, chairs and full-on centerpieces all in white.
Safe to say, this woman is one strong and unbelievable idol to many - but she keeps churning out the songs because, hey, we all deal with things differently and her creative outlet is hers to use however she wishes.
Watch Grande's performance of "thank u, next" on Ellen above.
She helped organise the One Love Manchester concert a year ago, raising more than $23 million for victims of the Manchester bombing.
As for the performance, it was definitely live as she almost took a faceplant trying to step down from a chair on the wedding reception-inspired set.
"We were supposed to come down?" "We love you, we support you".
Ellen and Ariana's interview has been one of the most highly anticipated chats in recent times as fans are hoping to find out more news on all this brand new music and people also look to find out what happened around Ari's split from Pete Davidson.
Ninety minutes after the song dropped, Davidson made his own statement during the "SNL's" Weekend Update segment, concluding his raucous guest spot by saying, "I know some of you are curious about the breakup, but the truth is, it's nobody's business".
