Justin Theroux announced on Instagram Monday that his and ex Jennifer Aniston's beloved dog Dolly had died
“We love you dolly 💔💔,” Cox, 55, wrote on Theroux’s social media post.
Cox’s message to Aniston, 50, and the Leftovers actor, 47, joined those of several other celebrity pals, including Olivia Munn, who commented nine red heart emojis, and Orlando Bloom, who wrote, “rip beauty.”
Theroux announced Dolly’s death on Instagram Monday with a sweet slideshow of photos that appeared to be from an outdoor burial ceremony with Aniston.
The pup was covered in flower petals as she was laid to rest and later wrapped in a white blanket. An additional photo shows two hands — one presumably Theroux’s and the other appearing to be Aniston’s — holding each other over the dog’s leg.
“Tonight, at sunset, after a heroic struggle… our most loyal family member and protector, Dolly A. laid down her sword and shield 🐺💔,” he captioned the post. “She was surrounded by her entire family.”
He also included a quote from former U.S. Senator George Vest that read, “The one that never deserts, the one that never proves ungrateful … is the dog- faithful and true, even in death.”
“I’m like Dolly,” the actress told Allure in 2011. “Her brain moves faster than her body, and she’s slightly klutzy, which I tend to be.”
“They are like Jen’s babies,” a source told PEOPLE at the time.
