Taylor Swift has a little help from her Friend Lisa Kudrow

Never thought I'd say this but "Smelly Cat" was on my set list last night. Taylor Swift famously described herself as being "obsessed with her friends." Living up to her reputation as the ultimate celebrity BFF, the singer has been inviting her besties to join her on stage during her 1989 sell-out world tour. The 52-year-old actress, who played struggling musician Phoebe Buffay in the sitcom for a decade joined Swift, 25, for a rendition of her character's famed comedy song Smelly Cat.
