It seems like she's doing everything she can to move on, but also honour the memory of her ex, as she has now taken ownership of his dog, Myron.
Ariana, who is already a huge dog lover, was spotted walking and posing for adorable videos with Myron this week.
Ariana already has six rescue dogs of her own: Pignoli, Coco, Cinnamon, Strauss, Lafayette and Toulouse.
Her mum, Joan Grande, also has five of her own dogs: Don Vito Corleone, Sirius Black, Ophelia, Francis Albert Sinatra and Madonna Luisa Veronica.
Adorable.
