Gang's (almost!) all here! The star-studded cast of beloved '90s sitcom Friends reunited on Sunday, January 24, and there's proof on Instagram that Jennifer Aniston (Rachel), Courteney Cox (Monica), Lisa Kudrow (Phoebe), David Schwimmer (Ross) and Matt LeBlanc (Joey) were all together. 

The photo, shared by actor Johnny Galecki, featured the famous Friends alums flanked by the cast of CBS' smash comedy Big Bang Theory. "And then this happened. #TBBT #friends," Galecki captioned the pic, which also featured his co-star Kaley Cuoco.

In the center of the snap was Aniston, 46, who beamed beside her real-life BFF Cox, 51. Big Bang Theory actor Jim Parsons, meanwhile, wedged himself in between Aniston and her onscreen love Schwimmer.

And then this happened. #TBBT #friends

The only one missing in action was Matthew Perry (Chandler), who previously said he could not attend the festivities at Sunset Tower as he continues to rehearse for his upcoming play, The End of Longing, in London.

The famous Friends group reunited on Sunday night to honor legendary TV creator James Burrows, who directed 15 episodes of the sitcom, including the pilot episode, during its run from 1994 to 2004. The network's chairman, Bob Greenblatt, told Us Weekly on January 13 that he believed most of the superstar cast would be involved in honoring Burrows, whose contributions to television include directing hundreds of episodes of Cheers, Frasier and Laverne & Shirley.

Friends cocreator Marta Kauffman also told Us that she would be joining the fun on Sunday night. "I will be there," she said, "but it is not a Friends reunion."

The two-hour special will air on NBC on February 21.
