Jennifer Aniston is telling everyone that it’s her birthday.

The “Friends” alum isn’t bragging, but she issued a huge thanks for all of the well-wishes she has received on her special day, even the one from her ex-husband Justin Theroux.

Aniston, 51, took to her Instagram Stories on Tuesday and displayed a message for all of her fans and loved ones, thanking them “for all the birthday wishes today. 11:11 2/11,” she wrote over a screenshot of the time (11:11).

That also meant thanking Justin Theroux, who Aniston was married to for two years before the pair announced their split in February 2018. They have remained incredibly cordial ever since.

"Grabbing 2020 & another year just like...," Theroux shared on his own Stories, along with a hilarious black-and-white pic of Aniston channeling her inner Incredible Hulk-gone-mad expression. "Happy Birthday B ❤️."

Many of Aniston’s friends in showbiz also issued their own tributes to the actress on their respective accounts.
