Jennifer Aniston ‘s Rachel Green had an unforgettable friend group on TV, but even the Central Perk crew may not have had bonds as strong as Jen’s real-life relationship with her Friends costars.

Jennifer Aniston celebrated her 56th birthday on Thursday and it wasn't just her fans sending the actress well wishes on her special day. Jennifer's Friends co-star and real-life bestie Courteney Cox took to Instagram to pay tribute to the fellow actress and also shared an epic throwback photo.

With the separation from Pitt racking up so much publicity, Aniston claimed a relationship with one of her co-stars ‘brought her back to life’. The 56-year-old has an impressive list of credits to her name and with a fair few rom-coms under her belt, plenty of A-list male co-stars she’s shared the screen with.

Jennifer gained global fame for her role as Rachel Green in the hit TV series Friends, which aired for 10 seasons from 1994 to 2004. Each episode made her even more beloved among fans around the world.
