Taylor keeps bringing out all these other musicians and actors and models at her shows on her 1989 Tour, but this guest beats all the others! There's no way she'll be able to top herself after this!

If you're a fan of Taylor Swift who also happens to be a fan of the show "Friends," then you're in for a real treat! At one of Taylor's shows in L.A., shr brought out special guest Lisa Kudrow, aka Pheobe! And what song is Pheobe best known for? That's right... "Smelly Cat."

TAYLOR AND PHEOBE PERFORMED "SMELLY CAT" TOGETHER. MY HEART IS SO HAPPY.
