Who in my opinion is the best?

You can already see through my profile photo. This is Ariana grande, beautiful as her voice. I love and love her panthers. He's my idol for 3-4 years.
My top 5 songs:
-To tears left to cry
-Quit
-Thinking bout you
-The way
-ador
I keep my fingers crossed for her career and I hope that I will meet sometime and take a photo of herself :D
