Knowing she did not hear a shit trough her in-ear makes me have more respect for her!

2:38 Man .... she climbs a ladder and still manages to hit that note. This girl is gold. Hahaha

Throwback to when she actually performed this song happy :,(

I love her😭😭😭😭😭😭😭Ariana's is the best singer in this generation

The girl has soooo much talent, how people can't say she's talentless and auto tuned is beyond me. The proof is right in front of you!

For people asking why she sounded out of breath: She couldn't hear anything she was singing. Her ear piece which is what singers use to hear themselves wasn't working. She was probably nervous so she was breathless. It was still good considering Mariah just had the same problem on New Years and completely flopped the performance.

Her voice is just the best THE BEST SHE LITERALLY HIT THAT HIGH NOTE WHILE WALKING

2:31 Her friend: Let me help you climbing up stairs Ariana: I can do this!

I love her 😭😭😭😭😭😭😭 Ariana's the best singer in this generation

This is a great song. In 20 years all you teenagers will hear this song and will get emotional, trust me. I'm 41 and it happens to me whenever I hear late 1980's early 1990's Freestyle music. Even seeing the cars, that you and your friends drive today, in 20 years will bring a tear to your eyes.

アリアナ様すごすぎます！もう尊敬しかないです！こんな歌声を持ってるのは世界に1人、アリアナ様しかいません！いつも元気をありがとうございます！ One last timeだいすきです！

Shouting at the beginning and singing high notes in the drop takes guts 🙏

Love her heels... anyone else?

love you forever and ever

i’m back after 3 years damn this good nostalgia i feel ✨ i was a baby arianator and obsessed with performances especially OLT and now it’s just emo how time flies..

0:39 'but i got nothing here without ya HAH'

did anyone realise how she struggled in her lower register and as soon as she got to her belts she was perfect. it’s just her comfortable vocal place.

2:31 -Guy tries to help her up the stairs *nah bitch I got this *he then tries to play it off nonchalantly like he didn't just get his feelings hurt

the way she ignored the thrown shoe by audience and hit that high note is so inspiring,she is so strong!!

I'm still crying Ari, this is sad and so cute ❣️❣️❣️🤗

She is pretty

I love Ariana, Only thing that would make her so much better is to take better breaks inbetween singing alot of the times she runs out of breath right at the end of a sentence cutting off her singing.

When you realise that she did this without her inears! WOWWW!

Sooo emotional 😭 that remember me to something (manchester) is so hard listen this song now... but that song have a place in my heart 🌸 #onelovemanchester

one last time has a new meaning

To those of you saying she's so out of breath: she just just sang bang bang n problem with a whole ton of choreography, she was shit tired & was performing for 80,000+ people so that can get someone nervous !!! Jusssss sayin

I'm in love with this performance 😍

I love u Ari!🧚🏻‍♂️

I'm crying. she does amazing EVERY SINGLE TIME! the fact that she couldn't hear anything through her in-ears and STILL sounds this amazing just blows me away! she's my everything and I love her so much. I'm so proud to be a fan ❤️

This song has a whole new meaning now, can't listen to it without getting emotional. Especially when you were at the concert that night, listening to all her fans singing their hearts out, not knowing it would be their last time for 22 of them . #prayformanchester 💔🙏🏻😢

I love you Ari so so so so much.❤💙❤❤❤💙💙💙💜💜💜💕💕💕

아리 고음 너무 좋다ㅜ 음색도 자기만의 개성있는게 너무 멋지고!!.😉

QUEEN. KEEP SLAYING ❤️

guys ariana explained her "bad" performance in her other channel called 'The Honeymoon Diaries'. her earplug thing (whatever it'd called lol) didn't work properly and she didn't hear a shit while performing. even tho this maybe wasn't her best performance, i think she did good job and some people rated this one of her best performances !! oh, you can't deny it, that in the end her high notes where amazing, can't you? ;)

Minha música preferida da Ariana. Essa música é perfeita !!

In these difficult days, listening to the joyful songs of Ariana Grande really feels like medicine 🔥😍😘💐

she sounds really good live

Don't ever say she sings terrible. I understand she was out of breath here, but that's because she dances, and sings heart her heart out. If you listen to other artists live like (Selena Gomez) you can hear that her voice is flat and has nothing special about it. But Ariana still slays high notes

how happy were the people who listened to this live...

i miss when this song was happy and so was she :(

Jesus what a dead crowd

Ugh!!! I FUCKING LOVE YOU !!!!!!!

I'll never get tired of hearing her beautiful voice, ilysm Ariana 😘😘😘

I love she voice. She is amazing , unique , beautiful and sweet .💞😉💖😘

I freaking love her every time I watch I just cry at how amazing she is pr

i really like your boot and your hairstyle 😘😍😍😍

I got chills watching this, she is the best

Really really really really really really really really really really really really BEAUTIFUL

This song breaks my heart ❤️ but I can't stop listening to it 😞. Thoughts and prayers to those who lost their love ones 😕 #prayformanchester #weloveyouari

Definitivamente la amo ♥

That choreography brings tears to my eyes. Love you Ari!

This world does not deserve her she is to perfect

She's not out of breath, she has underdeveloped chest vocals- meaning the lower register she goes the more she struggles. That's why her higher belts are amazing, listen to focus live, it's a few octaves higher than the main part of one last time, there's no struggling just amazing live vocals, slayariana❤️

2016 performance is superior to this. She's improved so much.

I really wish I could see her in person

I love this song so much💖 Ariana, you sing so perfect!

2:37 I saw someone throw one shoe on the stage.

I hate how the audience is not even energetic in cheering her but ariana anyway is woww asf😍😍😍

HER VOCALS ARE INSIDE MY HEART FOREVER SHE IS SOOOO AMAZING YOU HIT THAT NOTE YOUR SOOO GOOD OMG I LOVE YOU ARIANA SO MUCH

Can’t believe old song it. Feels like yesterday

that crowd was boring af they didn't do anything

Shes so out of breath ! Im getting out breath just watching her out of breath😂😂

I love her and her songs!!

I love her ♥♥♥Ariana's the best singing

I am just passing by all of her performances of this song, cause it is so sad what happened in Manchester 😿

Ariana can sing a lot better than this particular performance. Maybe she had a cold?

ARIANA I LOVE YOU!!! YOU ARE SOOO AMAZING🥺❤

She has such a great voice. She’s so talented and pretty. I LOVE HER WORK! Keep it up Ariana! ❤ Also this is my fav song!

A Beautiful young girl & a very beautiful Voice too. She obviously looks way younger than her age. This particular song has become very popular, as she, herself. Very nice song & the way she sings it also very touching. Love her MUSIC...

okay guys let me tell you something. You can't say Ariana sings like shit. She has got such a powerful voice and she is very talented. I agree with the part that she can't sing in this video. She got out of breath and it's not very good. But you know, she is a human too and things like this happen. Stop comparing her to other singers. Ariana, Miley and Demi has got the best voice, but c'mon, it you HAVE TO hate, go and spread your hate on Selena. P.S: I'm not saying go hate on Selena. Im just saying that IF Ari has hate Selena should too. Because you can't deny that Ari is more professional then Selena.

She is my everything its somthing i like it make my happy 💕😭

Such a great performer and ball of energy.

she sounds so out of breath but it's way better than I could ever do

Stay strong baby ❤

Perfect 🎧🎶💎🔥🔥🏹💔❤️

Look at all those ppl! She is so amazing ❤

2:37 - mds que voz maravilhosa é essa ♥

Não me canso de ouvir essa música...A voz da Ariana é magnifica !!!

Aw..this was when she was able to perform this song with no tears or sadness. I still cant believe what happened at her concert and I still wish the 22 angels everything 💖🕊 even though it happened a long time ago, i still pray for ari and the angels

one of my all time favorite performances!

Amo la voz de Ari. ❤

I hate how she's always yelling yeah or lets go or whatever in the middle of the song.

この曲一番好き！！

The tone of your voice is pure and innocent, like a feeling that descends from my lips to my heart. Ariana Grande 🔥😍😘💐

this song has a new meaning); #prayformanchester
