Ariana Grande's grandfather passed away

Ariana Grande's grandfather has passed away and the star has taken to Twitter to express her grief.

The 21-year-old singer dedicated a series of tweets to her grandfather, describing “how amazing he was.”

“If only y’all knew how amazing he was. My heart hurts so much. It’s beyond broken, but I got to hold his hand and watch him find his peace,” she tweeted. “This is the hardest thing imaginable but I’m so grateful that I got to spend this time with him and my family, taking care of him and loving him. We thank you so much for the continuous love.”

Ariana's grandfather, affectionately known as Grandpa Grande by the Arianator community, had been battling cancer for some time. In recent weeks, Grande had canceled promotional work to be by her grandfather's side, as he had fallen more ill.

According to Bustle, Grandpa Grande had a Twitter account of his own, where he often expressed how big a fan and how proud he was of his granddaughter.

Frankie Grande, the singer's brother who is currently competing on Big Brother, will remain unaware of the death in his family, as it seems she will be honoring Grandpa Grande's wishes to avoid Frankie's departure from the competition, reports TMZ.
