Smelly Cat is back: Pheobe joins Taylor Swift during concert

American singer Taylor Swift sung Smelly Cat -- from the hugely popular sitcom Friends -- during one of her concerts. The fun doubled when she invited Friends star Lisa Kudrow on stage to perform with her.

In case you have forgotten, Smelly Cat is the iconic song written by Kudrow’s character Phoebe.

Taylor is busy these days promoting her fifth studio album Taylor Swift's 1989. The 1989 World Tour is part of the promotions and is being made memorable by Taylor's famous friends appearing on stage than the singer's performances.

Lisa Kudrow clearly enjoyed singing the rendition of one of the most enduring songs from the series, tweeting afterwards: “So Taylor Swift is the best person I’ve ever met. That was fun. Thanks Taylor.”
