Videos: Taylor Swift Surprises With Justin Timberlake, Lisa Kudrow 'Smelly Cat' Performance

How do you end your five-day tour through Los Angeles when you've already brought every guest imaginable on stage with you (ahem Kobe Bryant and Alanis Morrissette)? Well, by going even bigger. Taylor Swift, drunk with bestie power at this point, got Justin Timberlake and Selena Gomez to join her, as well as Lisa Kudrow in character as Friends' Phoebe Buffay.

Yes, you better believe that Kudrow performed "Smelly Cat":

Tay-Tay even got Timberlake to take a little break from father duties since he hasn't been on stage since he and wife Jessica Biel had their baby daughter in April. She said at the Staples Center, "So Justin hasn’t performed since he became a dad, so I’m just honored that this is his first performance." They performed his song, "Mirrors" together, and Taytor Tot wore a sparkling blue ice skater-like number:

And what's the best part about being in T-Swift's #Squad? Getting to jump on stage with her like Selena Gomez did on Wednesday night. Swift captioned this photo on her Instagram with "Sisterhood":

They performed Gomez's "Good for You" on stage:

We don't know how Swift's going to top this 1989 World Tour performance as she moves to San Diego next, starting this Saturday. Just this tour alone, she's had John Legend, St. Vincent, Julia Roberts, Joan Baez, Cara Delevingne, Nick Jonas, Serena Williams, and the the U.S. Women's Soccer National Team join her on stage—and that's not even everyone in her exhaustive list. Hey, maybe she can take some cues from writer Lara Marie Schoenhals' comedic video about whom she should bring up next.
