Taylor Swift’s Latest Guests: Selena Gomez, Justin Timberlake + Phoebe Buffay

Once content to play for latte-sipping coffee shop-dwellers during their lunch breaks, Phoebe Buffay has finally performed for her deserved audience: Los Angeles' Staples Center.

Lisa Kudrow, who played the eccentric, guitar-strumming Friends character for 10 years, was one of Taylor Swift's latest guests along the country-turned-pop singer's 1989 World Tour. And though "Suicide and a Snowman" and "Ode to a Pubic Hair" were sadly overlooked, Buffay's classic "Smelly Cat" found its way onto Swift's set list.

"She's never played in a big venue like this, so please make her feel welcome," Swift says to introduce her guest in the clip above. In spite of the artists' disparate performance styles, Swift and Kudrow ultimately make for a folk duo with Lilith Fair potential. Still, the woman behind Phoebe won't settle for anything less than perfection, and stops the set at a spot she thinks could use some fine-tuning.

"That was good, but you have to really feel the lyrics, you know?" she tells Swift while in character. You'd be remiss to argue with Princess Consuela Bananahammock!

Conversely, Taylor found herself squarely in her element when she invited good pal Selena Gomez to the arena's stage for a rendition of "Good for You." Sexier? Perhaps, but we'd be lying if we said we weren't still distractedly humming "You may not be a bed of roses / You're no friend to those with noses" all the while.

Ultimately, it was the introduction of Justin Timberlake that seemed to please the crowd most — and the "Mirrors" singer seemed especially thankful to be featured at a 1989 show. Bowing outwardly to concert-goers: The new 20/20 Experience.

Check out the videos, and stay tuned to see who might make a cameo at T. Swift's next show in San Diego. Any guesses?
