Taylor Swift, Jennifer Lopez: Final 'RED' Tour Stop, Harry Styles' Ex Performs 'Jenny From The Block' With J. Lo [VIDEO]

Today in "LOL WUT?," we have Taylor Swift's final guest performance during her previously thought to be never-ending RED Tour. Previously, the "22" singer had brought out Tegan & Sara, Sara Bareilles and Cher Lloyd. At the tour's final stop, the Staples Center in Los Angeles, Harry Styles ex-girlfriend brought out Jennifer Lopez to duet on "Jenny From The Block."

I'll repeat that: TSWIFT, the person whose picture appears in the dictionary under "white people," brought J. Lo on stage to perform an ode to the South Bronx.

Taylor described it as her "hairbrush song," aka the song you sing into the mirror when you're all alone. Nothing I can say will add to that image.

Swift pulls off the performance a lot better than you'd expect. But I still can't help but be reminded of this Saturday Night Live gem.
