And now that longtime dear pal and former Friends co-star Courteney Cox has plans to tie the knot as well, we of course wondered whether Aniston was sharing wedding planning tips with her bestie.
Or, considering how much else the actresses have going on, do they even talk about such things?!
"We honestly don't talk about it," Aniston divulged to E! News during the junket for her latest film, Life of Crime, dashing our dreams of a real-life gab session complete with a Monica Geller-caliber binder full of wedding ideas.
But that doesn't mean Jen doesn't have advice for Courteney, who got engaged to Snow Patrol frontman Johnny McDaid in June.
Watch the video above to hear what Aniston advises Cox to do before she marries McDaid, whenever that day might come.
In the meantime, the dark comedy Life of Crime, based on the Elmore Leonard novel The Switch about a couple of crooks who kidnap the wife of a wealthy real estate developer who has no interest in paying their $1 million ransom demand, comes out on Friday.
