WATCH: Taylor Swift sings ‘Smelly Cat’ on stage with Lisa Kudrow

Forget her squad, forget her urge to surprise fans and her budding romance with DJ Calvin Harris - THIS may be the most exciting thing we’ve ever seen from Taylor Swift.

The ‘Shake it Off’ star performed the fifth and final gig of her record-breaking sold out shows at Staples Center in LA last night, and was determined to make it one to remember.

So, she invited Friends star Lisa Kudrow to the stage for a rendition ‘Smelly Cat’, a song made famous by her character Phoebe Buffay.

And yes, it was everything you ever imagined and more.

*cue our inner 90s child freak-out*

She also performed a duet of ‘All of Me’ with John Legend, ‘Mirrors’ with Justin Timberlake and ‘Good for You’ with bestie Selena Gomez - no biggie.
