Calling All Friends Fans! Phoebe Buffay and Taylor Swift Sang "Smelly Cat" on Stage

Taylor Swift's ever-growing list of celebrity cameos on her 1989 tour has grown by one more. Phoebe Buffay (Lisa Kudrow's character from Friends) joined Swift on stage for a rendition of the now-iconic song "Smelly Cat." This is not a joke. Clad in a classic Phoebe getup, Kudrow really taught Swift how it's done. Do yourself a favor and watch the video, and try to really feel the lyrics.

Here's another video, posted by the Staples Center:

And finally, Kudrow tweeted at her new friend, Swift:

So @taylorswift13 is THE best person I've ever met. That was fun. Thanks Taylor.

Swift also brought along Justin Timberlake and Selena Gomez. No big deal.
