Their chemistry is fucking amazing.

Their chemistry on stage and off stage is undeniable. They know how to put on a show. I'm vibing it so much. Both Camila and MGK are amazing and without either of them this would have never happened.

I'm glad MGK chose Camila for this song. Both are amazing especially on live performance.

Is this live? Seriously? I’ve never heard any artists sound this good live. Woah

camila's energy in this perfomance is a bomb!!! go girl. NUMBER ONE IS COMING

I melted every time he looked at her and smiled.

Her voice improved so much, I'm a proud parent

the way he look at her !😍😍

I like the way they look at each other as they sing. What can I say? I'm a romantic.

Camila is the queen of runs and note change.. 🔥🔥🔥

He's a genius and she can reach insane notes. Great performance.

I love how everyone screamed when mgk came out

THE WAY HE LOOKS AT CAMILA 😭💕

So did Camila work on this new arrangement while practicing for Jingle Ball performances? Like seriously, how does this girl do it all and do it so well?? Both of them are oozing with talent and musical creativity. Love that MGK picked up that guitar and THAT NOTE change towards the end...it's amazing to witness Camila unveil her true self/potential and be given the freedom to create her own music. I'm so impressed!

"I want you forever even if we're not together" aaaaaaaaa

I love how he's staring at her like he's in love with her

this song is really underrated

it's funny how James say MGK name while hugging Camila and saying Camila's while greeting MGK lol.. and I must say that Camila starting to embrace the bad girl vibe wearing that outfit..

I dont know if its just me... the way MGK look camila like, " she's so damn good im so lucky or so proud that I collab with her." aaaarrrggghh!

Better than the studio version

Wow... This was awesome.. 👏👏 also so different from what they performed in jimmy fallon..

My baby has done it again! This performance was amazing she killed all her runs and notes I was literally in heaven. MGK also did amazing I love their stage chemistry and all the arrangements it's surprisingly better than last time! This song is doing great

HONESTLY this is better live. Camila's voice is SO lovely in this song!

I love the chemistry they have together!!! :D ^^

ok MGK killed it.. so did Camilla as always but dam MGK's energy tho

Why are ppl ignoring mgk on this song? He is the man behind this song

4:09 Camila. Who told you that it was okay to do that? Because that killed me. Hope you're happy😍

the way he looks at her 1:48

let's talk about those vocals, i'm impressed

I love how versatile Camila is, like she fits in with any genre. The last performance was all princess like and now it's more of a rockish grungy sound. Again her chemistry with mgk is amazing. Camila looks so beautiful too keep slaying us 🔥🔥😂😭😭😩

I love this duo SO MUCH. I can't wait to see MORE live performances.

They should really do more music together they bring out the best in each other ❤

Oh God! This was more like the original song They slayed the night so much❤❤

okay ariana ft camila next

i love her how voice sounds the same whether it's live or in studio. true talent

I come back to this sometimes -- I just love the energy they created together on this song, electric. But the live versions are better than the studio one.

she is trying to make each performance different and she succeeded and MGk was amazing

4:07 Excuse my language, but I'm so fucking proud of Camila. I literally got chills from that note change. Yes, Mila, YES!

I can't pick between rewacthing this live preformance or the music video.. I will be replaying both non stop!

Camila.. She's my everything ! I love her so much 😭😭

Wow, Camila at the end!

she's was AMAZING !!! Number 4 on iTunes babyyyy!🙌 Congrats Camila and MGK ❤

Depois de 5 anos continua a minha favorita ❤️❤️❤️😭

I'M INLOVE WITH THEM WATCHING THIS RIGHT NOW....

THOSE RUNS AT THE END IM DECEASED. WHY DOESNT SHE DO THAT MORE WHAT ELSE ARE YOU HIDING FROM US 😭😭😭👌👌👌🔥🔥🔥😩😩😍😍😍

Camilita YOU NEVER FAIL TO SLAY🔥🔥🔥❤️✨

Great vocals, amazing instrumentals, overall a spectacular performance. So proud of Mila ❤️

KZfaq how did I just now find out that Camila and MGK collaborated?? I needed this

im dying for camilla just cant sleep woowww look her beauty makes me cry.. shes great talented in this generation. guys they must recieving award from this song!!

those notes coming from Camila at the end, made the performance for me

4:02 I love when they’re live she switches it up like that

She can really sing very well without the auto tune. Super Like !!

4:06 SURPRISING ME EVERY SINGLE TIME

I'm so damn proud of Kells, this is the kind of exposure he deserves, he's worked his ass off for things like this. They both seemed so much more comfortable here as well, and I appreciate that James went straight in for the hug and there was nothing awkward about it compared to the fairly awkward reception from Jimmy. And Camila is just as amazing as she usually is. Also James' acknowledgement to Rook as well just topped off how incredible this was.

"I want u forever even when we're not together scars on my body so I can take u wherever" hands down best part of the song

they are so cute together

I love it!! They make good chemistry together !! This was another good performance!!

Machine Gun Kelly and Camilla Cabello, The best performance ever!

I love it when she sounds the exact same thing as the audio recording. Proves that she doesn't need autotune! I want to do a cover of this song because it's in my vocal range and it's so easy to sing 😍 but I'm shy 😫

i think ariana and camila would be a power duo since they both have big incredible voices yet are tiny!

I didn't think it was possible to top their performance at jimmy fallon!! They DID that! Chemistry level 1000

Camila is gonna have a successful pop solo career i think. No shade to the other 5h girls. I think they'll all have good solo careers as well, but in terms of Pop, i think Camila fits best.

STILL THE BEST BAD THINGS PERFORMACE ❤️❤️❤️

This performance cures my depressive phase fr!😂

The studio, the sound, the runs and the changes of notes! Damn! This performance was a bomb! Really dope! I love it!

We've been using words for a LONG time, and still I can't figure out a way to express how much I love this queen....♥️👑

I literally can't stop watching this

I love her so much her OUTFIT WAS EVERYTHING

SO proud of Camz

can't believe I'm low key shipping them rn

This song is so good. I keep on listening to it so many times.

Definitely one of my favorite live performance

camila shined so much my baby i love you!

Can we talk about the fact MGK keeps looking at her the whole time? Like omg he has a crush.

i just love the way she say "COMPLICATED" 😌

Honestly MGK fans are so nice and not hateful towards Camila and I really appreciate that

The ending camila did is FUCKING giving me goosebumps!! SOOOOO GOODDDDD

she looks so, so cute at 4:16!!! 😍😄

I can feel something from the way MGK looks at her

YAAASSS That's my girl! they killed it!

MGK & Camila, one of the two have a crush on the other by now, if not the both of em. The chemistry, body language, eye-gazing, along with the 'friendly' stage touching..Yep. They would be a great couple though. The performance was awesome. Can't wait for it to hit #1 on the Top 100 Music chart. MGK, you deserve this shit man!! Enjoy it. Well earned my friend #EST4LIFE #EST19XX #CamilaIsADime #CamilaWillgoSoloEventually

camila her lil buns and her lil dance moves ahhhhh her voice is so fucking good

I'm in love with this song! WOW AMAZING and I love the way Camila enjoyed in the stage with MGK 👏👏😍

omg wow! i always love it when she sings the chorus but doing it live.. man! she's sooo good

First, Jimmy Fallon. Now, The Late Late Show. This song is slaying. I love this so much, omg. I'm so proud of Mila. You've come far alone, queen. But I hope 5H stays longer. Anyway, i love this but I prefer the one in Jimmy Fallon.Camila looked stunning there. Her perf was so raw too, since it's their first live perf. It was amazing. And her facial expressions in there were so captivating. Like, the way she winked and looked at the camera. Her moves were also full of confidence and not awkward at all. In here, she's awesome too but she looked awkward at times, it's cute. But overall, this is lit. SLAY! Credits to MGK as well.

4:06 Camila's voice omg

y'all are proud of Camila but god dAMN i'm so proud of MGK. 2017 is holdin big things for him

they r so cuuuuute together

I'm proud of you Cam

I'm so proud of her

2:23 Camila re creating Debby Ryans hair tuck

I kinda want a movie with her being the good girl and him being the bad boy (like his role in beyond the lights movie) being a bad influence on her! Lol so much chemistry 😂😅

Camilas voice is amazing

THE FALSETTO OR WHISTLE NOTE AT THE END I CANT BREATHE
