They’re still there for you, 25 years later. Rachel Green (Jennifer Aniston), Monica Geller (Courteney Cox), Phoebe Buffay (Lisa Kudrow), Joey Tribbiani (Matt LeBlanc), Chandler Bing (Matthew Perry) and Ross Geller (David Schwimmer) hit the small screen with a big bang in September 1994.
And as the world’s favorite “Friends” gear up to celebrate their 25th anniversary, we took a look back at 10 seasons to find some of the best celebrity guest stars who appeared alongside the famed cast of six.
Below are 25 of our favorite “Friends” celebrity cameos, listed in order of their appearance on the show.
