In celebration of the show's 20th anniversary in September, Friends stars Jennifer Aniston [1], Courteney Cox [2], and Lisa Kudrow reunited during a taping of Jimmy Kimmel Live in LA earlier this month. Jimmy hinted at the big reunion [3] when he posted a photo to Twitter, saying, "This happens tonight." The trio acted out a mock scene with the late night host in an exact replica of the NYC apartment from the show and even recited the famous theme song (although Jennifer staunchly refused to wear a "Rachel" haircut wig). We can't help but feel like we've been transported back in time seeing Rachel Green, Monica Geller, and Phoebe Buffay back in their old digs! Keep reading for the nostalgia-inducing photos and video of all the fun.
