Did Taylor Swift save the best for last?

Throughout the course of her 1989 World Tour, the 25-year-old "Wildest Dreams" singer has invited dozens of celebrities to join her in concert. This week alone, while headlining sold-out shows at the Staples Center in L.A., Swift shared the stage with Uzo Aduba, Mary J. Blige, Ellen DeGeneres, Matt LeBlanc, John Legend, Natalie Maines, Alanis Morissette, Sean O'Pry, Chris Rock and St. Vincent. For her fifth and final show at the venue, she recruited her BFF Selena Gomez, as well as actress Lisa Kudrow and music superstar Justin Timberlake.

With thousands of fans in the audience (including celebrities Miranda Cosgrove, Nina Dobrev, Jesse Tyler Ferguson, Calvin Harris, Julianne Hough, Jaime King, Ruby Rose and Emma Stone), Swift introduced her "best friend" Gomez before launching into the latter's song, "Good for You." (A$AP Rocky, who is featured on the single, did not make an appearance.) "After nearly 8 years of friendship, I just can't wait to tell our kids we ACTUALLY got to perform in front of thousands of insanely beautiful people together. TWICE! I love you Tay. #bestnightEVER #whatISlife," Gomez, 23, wrote in an Instagram caption. The pals previously performed Gomez's "Who Says" at Madison Square Garden in New York in 2011.

After Gomez left the stage, Swift said more surprises were in store.

That was understatement.

Just before her next guest made her entrance, Swift yelled, "Phoebe Buffay, everyone!" Kudrow, dressed as her Friends character, walked onstage with an acoustic guitar. Of course, the actress and Friends superfan performed "Smelly Cat."

The third and final performance came from Timberlake, who sang his 2013 hit "Mirrors." It was the first time the musician had been on stage since welcoming his firstborn son with wife Jessica Biel in April. "I have no way to deal with this," the singer-songwriter wrote in an Instagram caption. "Justin Timberlake is the BEST."
