The "Focus" singer invited her "Nonna," Marjorie Grande, to be her date for the musical evening Sunday. The silver-haired smiling beauty sat next to Grande in the audience and offered a congratulatory smooch on the cheek to her 22-year-old granddaughter when she was crowned Favorite Female Pop/Rock Artist.
While the younger Grande was visibly stunned to have been granted the award, she used her off-guard moment at the podium to pay tribute to Marjorie, who has joined her on many other red carpets in the singer's short but successful Hollywood career thus far.
"I think I owe a lot of this to my Nonna, who made who made sure to remind me that she voted," Grande admitted, putting her acting skills to the test as she began to impersonate her relative's Big Apple accent. "She goes, 'Ariana, I went on the computer. I voted, so I think you'll win.'"
The jury's still out on whether Marjorie was indeed the good luck charm Grande needed to win her second AMA after New Artist of the Year in 2013, but perhaps it's why these 12 other celebrities have brought their own beloved family members onto the red carpet with them.
