Taylor Swift And Lisa Kudrow Sang 'Smelly Cat' From Friends And It Was Beyond Words

Taylor Swift and Lisa Kudrow just performed 'Smelly Cat' together on stage.

Yup, that's right. Possibly the greatest pop duo combination the human imagination could possibly create.

Swift was headlining a sold-out concert at the Los Angeles Staples Centre as part of her epic 1989 tour when the she was joined by the 52-year-old actor.

The famously terrible song featured in a number of episodes of 'Friends', usually performed by Kudrow's character, Phoebe.

But in third season episode 'The One With Phoebe's Ex-Partner', the song got a professional makeover (albeit with someone else's voice).

So altogether now...

Smelly cat, Smelly Cat,

What are they feeding you?

Smelly Cat, Smelly Cat,

It's not your fault!

They won't take you to the vet,

You're obviously not their favorite pet,

You may not be a bed of roses

You're no friend to those with noses!

I promise you before we're done

All the world will smell as one!
