Demi Lovato and Kelly Clarkson: when dreams come true! 

And now she has done performances with both Christina Aguilera and Kelly.... DREAMS DO COME TRUE

Ten years. It’s just like when Demi said ten years ago that she wanted to sing the national anthem at the super bowl one day and SHE DID IT TEN YEARS LATER

I can definitely hear Kelly and Christina's techniques in Demi's voice. That being said, Demi has a very strong sense of self when she sings. Love both of them together <3

Kelly is a class act...she deserves all the fame and accolades she receives. And Demi....what a gigantic talent. This must have been such a blast for her. They sound amazing together. I will forever respect Kelly...for standing up for Dr. Ron Paul...for President. What's guts this woman has...it's a shame there are not more like her!

And now she has a Grammy nomination with Christina! 😭

my insparations are Demi Lovato and Kelly Clarkson!

You can tell that Demi was so excited to be up there with Kelly! They are both such amazing women!!

Please tell me I'm not the only one in tears from this...? :) too sweet

At the end Demi was fangirling over Kelly haha <3

Now they just need to make an album together :)

So it's 2015 and I still have a huge smile on my face everytime while watching this :D

I love how Demi is singing xtina's version and doing xtina's runs,

Okay... I admit it... I cried like a little girl! This was SO beautiful!!!! The duet AND the dream coming true! <3

Demi is the wonderful singer in the world!!!

Us hardcore Kelly fans are in love with the fact that Demi is such a huge fan. We consider her part of the fandom and were so excited when they sang this together <3

Man this video will always make me cry

kelly clarkson and demi need to do a song together on an album

Demi is the most wonderful singer in the world!!!

I wish they could get together and do other songs! Their voices are amazing together! I'm so happy for Demi and Kelly! Two beautiful women with power house voices and so down to earth. The two of them are inspirations!! Here is to dreams coming true!! Ok, I need to go hit replay again!!

I have loved Demi ever since Camp Rock and I have waited and waited to see her in concert and if I'm lucky I might be able to see her :3
