If you could build your own dream team of Hollywood besties, Jennifer Aniston would surely be top on the list.

The 51-year-old actress first won over the world’s collective heart in 1994, starring as the kind-of-spoiled but entirely good-hearted Rachel Green on Friends. In the nearly three decades since, she’s continued to infuse a humor and charm into her onscreen characters that makes her seem relatable off the screen as well.

But who actually gets to call Aniston a friend in real-life? From an ex-husband to a childhood bestie, here’s a closer look into the who’s who of Aniston’s friend group.

Jennifer Aniston and Courteney Cox played on-screen BFFs for 10 years as Rachel Green and Monica Geller. And in real-life, it’s not all that different. In addition to never missing each other’s birthday celebrations and dinner parties, the two have been a part of each other’s most monumental moments in life.

In 2004, Cox named Aniston the godmother to her daughter, Coco, with then-husband, David Arquette. And in 2015, Aniston asked Cox to be her maid of honor when she married Justin Theroux (Cox was also in attendance at Aniston’s 2000 wedding ceremony to Brad Pitt).
