Kelly Clarkson - "Heartbeat Song" and "Walk Away/Uptown Funk" [Ft. PTX] (Live in S.D. 8-16-15) 

omg kelly was so sweet with the "come on mitch!" "come on scott!" and the "show 'em girl!" to kirstie

I don't understand how they can run and jump and still be able to sing good. Me singing + stairs = dying cat.

I love Kelly. It's so incredible that she had them sing with her, and surprising in the kindest way that she gave Mitch, Scott, and Kirstie a verse for main vocals.

"Hey, let's all wear black and not tell Avi.."

I'm already a huge fan of Ptx and Kelly separately but my god they need to do a studio version of Heartbeat!!!

Wow, everybody still has huge amounts of bouncy energy for the finale. I love Kirsties shorts and long panel... and did you notice Scott had to make short steps or otherwise he would have trampled somebody as tall as he is. The kids' monotone black outfits let Kelly stand out with her colorful outfit. Thanks to the uploader for the clearest vid of the finale showing PTX and Kelly.

Everyone els3: *listens to Kelly singing Uptown funk* Pentaholics: *listens to hear Avi in the background*

Kirstie's part.....OMG IT WAS AMAZING

mitch and scott stayed jumping throughout heartbeat song haha

I was there when they sang this. Mitch killed me.🎶🎶❤️

Oh my God I was at that concert they were completely amazing they just blew my mind I was so happy that I went

i love how kelly isnt wearing shoes😂

Kirstin killed it!! She is amazing!!

4:31 The bass guy just looking at Avi 😂

I want a collab between Kelly and Adele. The two voices together would be off the chart!

Gotta say this bought tears to my eyes. They're all so genuinely happy to be there and you can hear it in their voices 😊

NO MATTER WHO AND WHERE THEY PERFORM ITS ALWAYS LIT

How do they make every song so much better!!!!!!

OMG Avi's Uptown Funk

I like how Kelly is barefoot and Kirstie has on really high heels and they are the same height lol Kirstie is so short bless her!

i liked this concert how it was so energetic and happy and fun👏🏼👏🏼

Did nobody notice Kelly and Kevin at 1:25?? Love this performance!

Mitch's lil look at Kelly still kills me

Avis dancing cracks me up

I want Kirstie's dress.

Full cover of Scott and Mitch singing Heartbeat Song but mostly Mitch

5:28 SHE LOOKS RIGHT AT THE CAMERA

Thanks so much for posting this, what a concert with a PTX bonus.

Pentatonix!!!

Everyone jumping around while Kirstie is wearing heels or boots

This is my heartbeat song and I'm gonna play it Been so long I forgot how to turn it up up up up all night long Oh up up all night long You, where the hell did you come from? You're a different, different kind of fun And I'm so used to feeling numb Now, I got pins and needles on my tongue Anticipating what's to come Like a finger on a loaded gun I can feel it rising Temperature inside me Haven't felt it for a long time This is my heartbeat song and I'm gonna play it Been so long I forgot how to turn it up up up up all night long Oh up up all night long This is my heartbeat song and I'm gonna play it Turned it on But I know you can take it up up up up all night long Oh up up all night long All night long I, I wasn't even gonna go out But I never would have had a doubt If I'da known where I'd be know Your hands on my hips And my kiss on your lips Oh I could do this for a long time This is my heartbeat song and I'm gonna play it Been so long I forgot how to turn it up up up up all night long Oh up up all night long This is my heartbeat song and I'm gonna play it Turned it on But I know you can take it up up up up all night long Oh up up all night long Until tonight I only dreamed about you I can't believe I ever breathed without you Baby you make me feel alive and brand new Bring it one more time, one more time This is my heartbeat song and I'm gonna play it Been so long I forgot how to turn it up up up up all night long Oh up up all night long This is my heartbeat song and I'm gonna play it Turn it on But I know you can take it up up up up all night long Oh up up all night long This is my heartbeat song and I'm gonna play it Been so long I forgot how to turn it up up up up all night long Oh up up all night long This is my heartbeat song and I'm gonna play it Turned it on But I know you can take it up up up up all night long Oh up up all night long

This is beautiful. I have no other word. Beautiful. Thank you 😍

They're all having so much fun! What a joy!

I Love this song😍😍😍

I love this!

This is AMAZING !

Lol I never noticed she wasn't wearing shoes!

I like that they started the same way!!!

PENTATONIX. IM DEAD

couldnt tell if kevin was just really good in the background or if there was a whole band playing

is kelly really small or is ptx a family of giants or both?

First song: where does the band end and Kevin/Avi begin? That awkward moment when you can't tell... Second song: "I'm such big fans so start us off on the next song and leave the stage so back up singers can work." BUt why does it still sound like Avi?

I want to hear the studio version..

im like, kevin and a drummer? avi and a bassist? o___O wth.. im confused.. but at least they get to rest ? HAHA

Shake it, Avi!!!

OMG It's the ChairGirl song!

She should have River come out and sing this one since it’s her fave.

AVI AMIRITE LADIES

What was up with mitchies voice😔

Okay apparently no one else is acknowledging the elephant in the room, so I'll ask. When did Kelly get so heavy? I mean, I havent been keeping up with her that much, but I remember seeing her in her AI days and she was smoking hot. Then I saw her a few years later after AI and she had gained a little weight but it wasn't bad. Now she's getting up there near the obese category. What happened?
