Taylor Swift continues to surprise us with just how many celebrity cameos it's possible to fit into one tour. So far everyone from Julia Roberts to her crew of model BFFs, to Little Mix and err Matt Le Blanc have joined Taylor on stage during her* 1989* concerts. And her latest collaboration was with a second Friends star: Lisa Kudrow. And this one has really made our day, as the pair sung Phoebe Buffay's song Smelly Cat.
Lisa was a surprise guest for Taylor's final sold-out date at LA's Staples Centre and arrived on stage guitar in hand, before launching into the song she famously sung in Central Perk. The audience loved it and so did Lisa, who took to Twitter after to call Taylor "THE best person I've ever met." She added: "That was fun. Thanks Taylor."
But Lisa's wasn't the only guest appearance of the fifith night at the venue, Bad Blood video star Selena Gomez was the first star of the night to join Taylor for a duet. The pair strutted down the runway singing Selena's new hit Good For You. And next up Justin Timberlake hit the stage to sing Mirrors with Swifty.
Though we know what our favourite moment of the night would have been...
