LOS ANGELES (AP) — Who would have thought a ticket to see Taylor Swift perform in Los Angeles the other night would have gotten you in to hear her do a duet of “Smelly Cat” with actress Lisa Kudrow? Taylor teamed up with the “Friends” star to perform Phoebe’s ode to the funky feline. It wasn’t the night’s only collaboration. Justin Timberlake teamed up with Swift to do the song “Mirrors.” And Swift joined Selena Gomez on “Good For You.” Swift’s performance Wednesday wrapped up her five-night run at the Staples Center in Los Angeles.
