Jennifer Aniston celebrated Thanksgiving with her newest fur baby, Lord Chesterfield.

The "Friends" alum shared photos of her with Chesterfield on Instagram. The pictures show Aniston striking a pose and playing with the pup. In the caption, Aniston shared how she was feeling by writing, "We're grateful."

Aniston's post was flooded with sweet messages and many praised her pet.

"This dog has star quality," David Spade wrote.

"I need to rescue this pup he’s clearly being abused! On my way!" Whitney Cummings jokingly wrote.

"Happy Thanksgiving, Lord and Lady," Laura Brown added.

"Happy Thanksgiving to fabulous you and fabulous Lord Chesterfield!" Laura Lynne Jackson wrote.

Aniston's ex-husband Justin Theroux also noticed the post and left clapping hands, folded hands and a red heart emoji. Theroux's comment on Aniston's post didn't go unnoticed to some of Aniston's followers.

"How come u got divorced but u r sending her hearts?? Weeiiirddd," one asked.

"So sweet," another commented.

"Such a gentleman," another wrote.

Aniston and Theroux remained good friends after their divorce. In fact, last year, they celebrated Thanksgiving together with Aniston's friends Courteney Cox, Jason Bateman and Jimmy Kimmel at Aniston's residence. The "Murder Mystery" star loves hosting parties at home, but she probably skipped that this time because Aniston's photos didn’t feature any celebrity guests.

Aniston and Theroux spending the holiday together sparked rumors. There were even speculations that Aniston was "hopelessly stuck" on her ex-husband. However, those were just speculations because Aniston is on good terms with her exes not just with Theroux. In fact, she's amicable with Brad Pitt and John Mayer.

Also, Aniston and Theroux shared pets when they were together. When their pet Dolly, a white shepherd, died in 2019, they reunited.

"Tonight, at sunset, after a heroic struggle... our most loyal family member and protector, Dolly A. laid down her sword and shield. She was surrounded by her entire family," he wrote on Instagram.

Meanwhile, Aniston introduced Lord Chesterfield in October. She shared a clip of of Chesterfield  sleeping with a bone in his mouth on social media.

"Hi! I’d like to introduce to you the newest member of our family….this is (a very tired) Lord Chesterfield," she wrote in the caption.
