Ariana Grande celebrates MTV VMA win by partying with Pete Davidson AND her grandmother

Ariana Grande’s grandmother proved age is just a number as she partied with the pop star into the early hours after the MTV VMAs.

Marjorie Grande, better known as ‘Nonna’, joined her granddaughter as they celebrated her Best Pop Video win for No Tears Left to Cry on Monday night.

Ariana’s fiancé Pete Davidson held onto Nonna as they headed inside the After Party Concert at Irving Plaza.

Nonna was dressed for the occasion in a metallic jacket while Ariana opted for knee high black boots and an over-sized fleece.

Ariana invited Nonna, her mother Joan and her cousin Lani on stage earlier in the evening as she performed God Is A Woman at the awards bash.

The Dangerous Woman singer frequently gives shout outs to her beloved grandmother who also has Pinterest boards dedicated to her online.

Ariana was among the night’s big winners and paid tribute to her fiancé as picked up the Best Pop Video gong.

“Thank you Republic, thank you Scooter, thank you Rashad my tour manager slash dad, I love you,” she said. “Thank you to my family who’s here today, my friends, and everyone, I love you. Pete Davidson. Thanks for existing. Love you.”

The pair had been inseparable earlier in the evening, with Davidson smothering the singer in kisses as they posed for photographers on the red carpet.

Ariana recently opened up about meeting the comedian, saying she knew “100 per cent” she would marry him.

He also has the seal of approval from Nonna, with Ariana telling Zach Sang: “Nonna loves him. She's very happy. Low key wants him.”
