Ariana Grande Dedicates AMA to Her Beloved Nonna (Video)

Ariana Grande poses with her trophy in the press room at the 2015 American Music Awards held at the Microsoft Theater on Sunday (November 22) in Los Angeles.

The 22-year-old singer won the award for Favorite Pop/Rock Female Artist at the show and she gave an adorable acceptance speech in which she thanked her Nonna.

“I think I owe a lot of this to my Nonna, who made sure to remind me that she voted. She goes, ‘Ariana, I went on the computer. I voted. So I think you’ll win!’” she said.

Make sure to watch Ariana‘s super sexy performance of “Focus” from earlier in the show!

FYI: Ariana is wearing a Giambattista Valli Haute Couture dress, Dsquared2 shoes, and a Lydia Courteille ring.
