The 'Friends' actress was in Edinburgh to support her boyfriend, Snow Patrol's Johnny McDaid.
Jennifer Aniston, Courteney Cox, Matt LeBlanc, Matthew Perry, Lisa Kudrow and David Schwimmer would all feature.
After teasing us here and there, the actress officially joined, making it her first and only official social media account.
Courteney Cox said of going too far with fillers: "I didn’t realize it until one day I... went, ‘Oh (expletive). I don’t look like myself."
