While Nancy O'Dell was interviewing LeBlanc, Kudrow happened to be walking past them. After an audible, "Yay!" the 52-year-old actress joined her old pal for a chat with ET -- but not before they complimented each other on looking great.
Both LeBlanc and Kudrow were nominees at Sunday's Emmys -- for Outstanding Lead Actor and Outstanding Lead Actress for their shows, Episodes
and The Comeback
, respectively -- and the 48-year-old actor told O'Dell that it was "nice" to be nominated along with a friend.
"[It feels] great," Kudrow reiterated. "What else is there to say?"
After LeBlanc turned to his old pal and said he was proud of her, Kudrow said, "I'm proud of you, too. That's what there is to say."
If you needed any more proof that they're still close, Kudrow revealed to ET that LeBlanc was actually the one who first told her she was up for an Emmy this year. "I texted her first," he said. "She didn't know."
"It was fun," she admitted.
The two just missed being reunited last month during the Los Angeles stop on Taylor Swift's 1989 World Tour
. LeBlanc strutted down the catwalk
alongside the "Bad Blood" singer, Chris Rock and Sean O'Pry on Aug. 22, and three days later, Kudrow serenaded Swifties
with her Friends
' character Phoebe Buffay's infamous song, "Smelly Cat."
"It was fun," the actress said of her duet with Swift. "She knows ["Smelly Cat"] better than me."
It was pretty great seeing her and LeBlanc looking as chummy as ever. Friends forever!
