“Smelly Cat,” the iconic musical number from Friends, made a roaring comeback after Lisa Kudrow, aka Phoebe Buffay in Friends, took to the stage to croon an ode to the world's stinkiest cat with Taylor Swift.
After it debuted in the second season of Friends, "Smelly Cat" was an instant classic.
Although Swift has had several celebrities join her onstage during her 1989 World Tour, nothing beats performing alongside the Friends cast member.
Fans of both Swift and the sitcom were extremely excited and posted their reactions on social media as they tweeted images and clips of the final Los Angeles concert.

Apparently, Kudrow seems to be as happy as fans are, tweeting:
So @taylorswift13 is THE best person I've ever met. That was fun. Thanks Taylor.— Lisa Kudrow (@LisaKudrow) August 27, 2015
The final show of the tour also included special guests like Selena Gomez and Justin Timberlake, who joined Swift on stage to sing a song or two. Check out the video above!
