Taylor Swift shocked the world last night by bringing out Jennifer Lopez at a concert in Los Angeles' Staples Center. Lopez came out and performed her classic song "Jenny From The Block." Swift introduced the moment by declaring "Jenny From The Block" as her favorite song growing up, saying that she used to sing it into her haircomb, pretending that it was a microphone.

Swift showed her love for the song by dancing and strutting right along with Lopez throughout the entire performance. She certainly used a few moves last night that have likely never been seen before at a Taylor Swift concert. The unconventional moment likely had some fans scratching their heads, as "Jenny From The Block" came out eleven years ago. Watch the performance above.

This was the second of two sold out dates in Los Angeles as part of her nationwide RED Tour. The previous night, Swift brought out Ellie Goulding as a guest. Later tonight, Swift heads out to Brooklyn where she is nominated for the MTV Video Music Awards. This will be the first MTV VMA where both her and Kanye West will be in the same venue.
