Watch: Taylor Swift and Lisa Kudrow Sing 'Smelly Cat' From Friends

Throughout her 1989 tour, Taylor Swift has treated her audiences to an array of suprise guest appearances, from Justin Timberlake to Ellen DeGeneres. Last night, at her last performance in Los Angeles, Swift teased a guest who has "only ever played in coffee houses before." "She's never played in a big venue like this," she added, before bringing out Lisa Kudrow, reprising her iconic and lovably character from Friends, Phoebe Buffay.

The two then went on to sing a rendition of 'Smelly Cat,' even re-enacting her character's interruption and instruction of guest star Chrissie Hynde in a 1995 episode.
