Lisa Kudrow is Taylor's latest celebrity pal to be invited on stage during her concert and we are seriously jealous we were not in the audience. 

The Friends star provided heaps of nostalgia when she appeared with her guitar to give a rendition of one of Phoebe's greatest moments.

The crowd was transported back to the Nineties with the duet at the sold-out concert in the Los Angeles Staples Center last night. 

It was completely perfect.

Lisa then took to Twitter to thank Taylor following the concert saying: "So @taylorswift13 is THE best person I've ever met. That was fun. Thanks Taylor."

Also performing with Taylor last night were Justin Timberlake and Selena Gomez, but we think this Smelly Cat rendition probably stole the show.
