Taylor Swift gave fans of 'Friends' a throwback moment to remember last night as she invited Lisa Kudrow on stage at the Staples Centre in Los Angeles to perform a duet of the Phoebe Buffay classic ‘Smelly Cat’.

Usually only heard in the intimate confines of Central Perk, 'Smelly Cat' got a stadium reworking and a full-throated sing along from the crowd.

And it seems Ms Kudrow quite enjoyed the experience

So @taylorswift13 is THE best person I've ever met. That was fun. Thanks Taylor.
