The 27-year-old pop star posted several photos of her Christmas celebration that also included her mother Joan, older half-brother Frankie Grande, 37, and best friend Doug Middlebrook, 25, and simply captioned them ‘merry :)’ for her roughly 212 million followers.
Ariana and Dalton, 25, wore matching black tops as they posed cheek-to-cheek in front of a Christmas tree.
The Grammy-winning singer also posted a group photo in the kitchen with Doug smiling while standing between her and Dalton.
Ariana had her long dark hair pulled back and accessorized with hoop earrings while wearing a black top and blue jeans in the photos
She also shared a snap of a Christmas tree adorned with white lights and large bulbs.
Ariana as a Christmas treat gifted hundreds of young hospital patients in Manchester, England with £100 Amazon vouchers.
She made the generous donation to patients at the Royal Manchester Children’s Hospital and Manchester Royal Infirmary, three years after her concert in the city ended in a devastating bombing that killed 22 people.
