To commemorate the grand occasion, Cox later took to Instagram herself shortly after Aniston shared her first post, and welcomed the actress to the wonderfully insane world of directly interacting with people on the internet.
"Hi Jen!" Cox captioned an adorable snapshot of herself and Aniston hugging and smiling. "Welcome to the social media world...it sucks. You’re gonna love it!"
As Friends fans know, the caption was referencing a line Cox's Monica Gellar says to Aniston's Rachel Green in the first season of the hit sitcom. "Welcome to the real world! It sucks. You're gonna love it," she tells her pal.
