Lady Gaga had an emotional night on Sunday.
Gaga, 32, posted the sad news on her Instagram, including an image of her and Arabella on a stunning ride in front of the ocean.
“Goodbye, my angel 💔,” Gaga captioned the post.
The second image of the post featured a tribute Gaga penned.
“I am so honored and blessed to have won both Best Song and Best Actress alongside Glenn Close this evening,” Gaga began. “My heart is exploding with pride. But it saddens me to say that just after the show I learned that my dear angel of a horse, Arabella, is dying. I am rushing to her now to say goodbye. Her name means ‘yield to prayer’. She is and was a beautiful horse.”
“Our souls and spirits were one,” the Star Is Born actress continued. “When she was in pain, so was I. I will never forget the moments we shared. Long hikes together, galloping through the canyons. Feeding her cookies. She will forever be a part of me. I am so very sad. But I wish for your pain to end, and the gates of heaven to open for you. I love you. Girl, where do you think you’re goin’?”
Gaga posted another image of the horse on Instagram later in the night.
Earlier that evening, Gaga won two trophies at the Critics’ Choice Awards: best song and best actress, which she split with fellow winner Glenn Close in a tie. The first award was for her original tune “Shallow,” featured in her and Bradley Cooper‘s movie A Star is Born, and the second for her role in the film.
“I’m so very happy that you won this evening,” Gaga told Close, 71, after the two shared a warm embrace. “This is a tremendous honor.”
“Bradley, you are a magical filmmaker,” Gaga said of her director and costar, 44. “And you are just as magical of a human being.”
“I’ve never had an experience with a director or an actor like I had with you and I will cherish it forever,” she added.
Gaga also thanked Cooper after her best song win, tearing up in her emotional speech.
“I’ll never forget playing [“Shallow”] for Bradley [Cooper] for the first time and seeing his face light up and then singing it live together, take after take,” she said as Cooper smiled while watching her speak. “I was mesmerized both as myself and as my character Ally. I was basking in the brilliant transformation of Bradley into Jackson Maine, singing on his stage, and overwhelmed by the storytelling and power in his voice.”
