The Big Bang Theory stars Kaley Cuoco and Johnny Galecki were also present at the celebration and shared a photo with the Friends cast on Instagram. Galecki captioned the snapshot, "And then this happened. #TBBT #friends."
NBC's two-hour tribute to Burrows will air Feb. 21 at 9 p.m. ET. In addition to Friends and The Big Bang Theory, Burrows is known for his work on Cheers, Frasier and Will & Grace, whose casts also reassembled to film the TV special.
Noticeably missing from the Friends reunion was Matthew Perry, who was rehearsing for his forthcoming play, The End of Longing, in London. The 46-year-old actor recently told BBC Radio Two he believes the cast would be open to a reunion special.
"I think we would be open to doing something," he told host Chris Evans. "Some kind of maybe TV special. I don't know about a movie. It's kind of tough because [Friends] ended on such a high note that we don't want to ruin it. We'd want to be really careful."
"Sometimes when you do a reunion it's terrible and it sort of ruins the memory of the good show that you've done before," he explained. "We've talked about it a little bit over dinner. We like to get together for dinner and we have a good time together."
Friends had a 10-season run from 1994 to 2004. Aniston starred as Rachel Green, with Cox as Monica Geller, Kudrow as Phoebe Buffay, Schwimmer as Ross Geller, LeBlanc as Joey Tribbiani and Perry as Chandler Bing.
