For celebs, being on a long-running TV show is more than what you do on screen — sometimes the relationships extend off-set, too. Co-stars like Jennifer Aniston and Courteney Cox have stayed friends way pay the finale of their show — and so have these other co-stars.

Speaking of Jennifer and Courteney, they've been friends for years, with Jennifer even babysitting Courteney's daughter, Coco.
"I let them play with my clothes and jewelry," Jennifer said in 2016. "I put them in the pool, put 'em in a tub, put 'em in your jewelry, give 'em your jewelry drawer."
Jennifer also stays at Courteney's house often, too.
"I've slept in her guest bedroom a lot," Jennifer said in a 2014 More interview. "Without giving away too much of my private stuff, all I can say is she's been there for me through thick and thin."
Courteney agrees that they both share a strong bond.
"We just have fun, we laugh, we're inseparable and it's great," she told TV Week.
Aww, Rachel and Monica for life!
