Friends forever.

Courteney Cox posted an Instagram selfie with her BFF and former “Friends” co-star Jennifer Aniston, delighting their fans with their sweet reunion.

Cox also showed support for Aniston’s haircare line, Lolavie, by sharing a snap of the brand’s products — including a shampoo and a conditioner — in the shower next to her own Homecourt body wash.

“We look so cute next to each other….so do they 😉♥️,” Cox wrote.

Actress Michelle Monaghan commented of Cox and Aniston, “This duo. ❤️🙌❤️.”

“My favorite duo this life and whatever comes after!!!!” another excited user gushed.

More “Friends” fans flooded the comment section to express their happiness at seeing the iconic television characters Rachel (played by Aniston) and Monica (played by Cox) together again.

“Rachel and Monica!! ❤️ I LOVE THIS FRIENDSHIP SO MUCH,” one comment read.

“I’m watching friends again and I love you both so much ❤️,” another comment said.

Aniston, 56, and Cox, 61, have remained close after “Friends” wrapped 21 years ago. Cox attended Aniston’s Friendsgiving celebration last November, and Aniston is the godmother of Cox’s daughter, Coco Arquette.

Aniston recently spoke out about their “Friends” co-star Matthew Perry and his tragic death in October 2023 due to a ketamine overdose.

He was 54 years old.

“It almost felt like we’d been mourning Matthew for a long time because his battle with that disease was a really hard one for him to fight,” Aniston told Vanity Fair in an interview published last week, noting that she and her fellow co-stars “did everything [they] could” for Perry during his long struggle with drug addiction.

“As hard as it was for all of us and for the fans, there’s a part of me that thinks this is better,” she continued.

She clarified that she is “glad” Perry is now “out of that pain.”

“Friends” — which starred Aniston, Cox, Perry, Lisa Kudrow, Matt LeBlanc and David Schwimmer — aired for 10 seasons from 1994 to 2004.
