Earlier in the week we told you that Demi Lovato had called Ariana Grande "the next big thing" in music.
"She has vocals that are just unbelievable, and I have so much respect for her because she is a true singer," Demi said. "She's someone that I feel like is going to have a long career because of her voice, and I think she's going to be a huge name. She's gonna be great."
Now, thanks to a mashup of "Heart Attack" and "The Way" created by Ariana's brother, Frankie Grande, we know just how awesome a collaboration between these two talented ladies would sound.
We're convinced. They need to make a song together!
