Fans have been tuning in to Twitter and Instagram daily to see who Taylor Swift decided to share the stage with at her most recent show, and thus far, she has yet to disappoint. This time, however, she may have outdone herself.

Lisa Kudrow, best known for her role as Phoebe Buffay on the NBC sitcom Friends, reprised her character to duet with Swift on one of Phoebe’s greatest quirky coffee house hits, “Smelly Cat."

Swift and Kudrow both strummed on acoustics and sang their hearts out while the audience sang along with gusto, completely blowing the minds of fans of both the Friends star and Swift. It was clear that Swift is also a huge fan of the sitcom — and Kudrow herself, who has continued her career with appearances on shows like Scandal and starring in a popular web series titled Web Therapy.

This unique pairing is not the first time Swift has ventured outside the realm of musicians to bring on stage, most recently including Ellen DeGeneres, Kobe Bryant and even Kudrow’s Friends costar Matt LaBlanc, who played Joey.

The show was Swift's final Los Angeles concert on her 1989 World Tour, and she definitely went out with a bang, including additional appearances by Justin Timberlake and bestie Selena Gomez. Swift has also performed with country artists Natalie Maines of Dixie Chicks and Sam Hunt so far on the tour, which continues through December.
