The classic sitcom's leading ladies reunited at Craig's restaurant in Los Angeles. After being BFFs for more than 20 years, the trio sure had a lot to talk about, leaving separately after dining for almost three hours, a source tells PEOPLE.
"They had a girls' dinner to celebrate Courteney's engagement," the source says. "They had a great time and enjoyed catching up over dinner for several hours."
Cox, 50, is set to wed Johnny McDaid after the Snow Patrol rocker popped the question in June.
Hopefully, she and Kudrow, 50, also raised a glass to Aniston, 45: She's been happily engaged to The Leftovers star Justin Theroux for two years.
Another Friend who joined the reunion dinner – albeit through FaceTime – was Matt LeBlanc.
"I just happened to FaceTime Courteney and she's like, 'Look who I am with!' I was like, 'Oh, wow, that's good,' " he told PEOPLE Thursday night at a Showtime event in Los Angeles. "It's hard to get together because everyone is all over the place."
And though he's given his stamp of approval on Theroux ("I met Justin and he's really nice!"), it sounds like another reunion is in order – this time including McDaid.
"I have not met Courteney's guy yet, so I need to get on that ... I need to get the baseball bat and go over there," he said, laughing.
In all seriousness though, "If they're happy, I'm happy," he added.
