Is Demi a fan of Ariana?

I's so awesome to see female singers supporting one another. Demi's been a huge supporter of Fifth Harmony, and now, she's praising Ariana Grande! "She has vocals that are just unbelievable, and I have so much respect for her because she is a true singer," she says. "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!"
