[WATCH] Taylor Swift Sings “Smelly Cat” with Lisa Kudrow

Fans of both Friends and Taylor Swift got their dream last night, especially those in Los Angeles.

Taylor played her final 1989 Tour show at Staples Center in L.A. and had a special surprise for everyone in the audience.

She's been bringing special guests on stage throughout the tour (Sam Hunt in Chicago, Seahawks QB Russell Wilson in Seattle, etc.), but last night she might have saved her best for last.

Taylor brought out Lisa Kudrow and the two did a duet of Kudrow's character Phoebe's hit song from Friends "Smelly Cat".

WARNING: This quite possibly could be the greatest thing you've ever seen, so brace yourself.
