The trio, who have been yes, friends, since starring together on the '90s hit show, captured their mini reunion with a smiling selfie.
"How lucky am I to celebrate my birthday with these two??? I love you girls. So much," Cox captioned the post, which was followed by a heart emoji.
Readers know Friends was the relatable sitcom that made television icons and long standing pals out of Jennifer, 50, Courtney, Lisa, 55 and their fellow cast mates Matthew Perry, 49, Matt LeBlanc ,51, and David Schwimmer, 52.
Ever since the show ended its long hit run in 2004, a Friends reunion was hindered by individual struggles and conflicting schedules, but the group, with the exception of Perry, was able to come together a few years ago.
Following their reunion, RadarOnline.com reported some of the friendships within the group were crumbling.
In one instance, Aniston was said to have befriended country legend Dolly Parton, 73, while they filmed for their movie Dumplin. A source said the budding friendship between Aniston and Parton was reported to have replaced https://radaronline.com/videos/jennifer-aniston-dolly-parton-friendship-movie/ that with her best friend Cox.
"They always got along and want to work together again. But Jen's always busy with a million projects, so Courteney didn't even bother asking her to join them."
Fortunately, the girls' recent get-together proves at least three of them are still on great terms!
