Arabella is a Arabian mare white female horse, a gift for her before Christmas on December 22, 2015 from Interscope Records. Gaga revealed in an interview with V Magazine that her life changed when her record label gave her a horse. Gaga said that when she got Arabella, she knew nothing about riding a horse. But she chose to give it a try and "grabbed her by the mane and rode her bareback."

In 2016, Gaga got her a boyfriend, a stallion named Trigger and they have two foals named Gracie and Sandy.
