Taylor Swift brings Selena Gomez, Timberlake on stage

Singer Taylor Swift pulled out all the stops during her last performance in Los Angeles Wednesday as she invited Selena Gomez, Justin Timberlake, and Lisa Kudrow onstage.

The sold-out Staples Center crowd was treated to a surprise performance of "Good For You" when Swift first brought out close friend Selena Gomez to sing a duet of the hit song. "It was a major girl power moment," one audience member told Us Weekly. "Afterwards Selena and Taylor seemed so excited about how well the performance went."

Next the "Blank Space" singer announced to the crowd that they had a coffee shop performer in the house, referencing Lisa Kudrow's character from Friends as she she appeared onstage, guitar in hand for a performance of "Smelly Cat."

"So @taylorswift is THE best person I've ever met," Kudrow tweeted out after the concert. "That was fun. Thanks Taylor."
