Jennifer Aniston celebrated her 49th birthday with Courteney Cox and other pals.
Aniston's manager, Aleen Keshishian, was among those to document the party on social media.
Keshishian shared a photo Monday on Instagram of Aniston posing with her friends in Cox's backyard.
"#happybirthday to my sister from another mother #jenniferaniston [love] u so much!" she captioned the picture.
The pair will co-star in a new Apple television series.
"Happy Birthday to my work sister #JenniferAniston!! Wishing you a day filled with lots of love and laughter! #HBD," Witherspoon wrote.
She discussed the possibility of the show's revival in an interview with "The Ellen DeGeneres Show" this month.
"Anything is a possibility, Ellen," the star said. "Anything!"
