Ariana Grande dedicated her American Music Award to her "nonna".
The 'Break Free' hitmaker was honoured with the gong for Best Female Pop/Rock Artist of the Year last night (22.11.15), beating the likes of Meghan Trainor and Taylor Swift to the crown, and thanked her grandmother in an emotional tribute.
Through tears, she said: "I just want to thank my fans - I have the most incredible fans. Ew I'm crying! But I love you guys. Thank you so, so much.
"I also want to say thank you to my family who are here tonight. I owe a lot of this to my Nonna!"
The 22-year-old singer also revealed her grandmother had predicted her win ahead of the ceremony.
Recalling what Marjorie said to her, she added: "'Ariana I went on the computer. I voted, so I think you'll win.'"
Meanwhile, during the star-studded ceremony, Ariana made her first televised performance of her track 'Focus'.
She ditched her famous ponytail, leaving her brunette locks flowing, whilst she opted for a sophisticated Hollywood glamour look.
Half way through the song, she went over to a lucky audience member, who pulled one of her gloves off with his teeth before she disappeared behind a red curtain to change into something more skimpy.
