Taylor Swift brought Jennifer Lopez on stage during her concert last night (August 24) at the Staples Centre in Los Angeles to perform a version of Jenny from the Block.
"I don't know about you but when I was a little girl . . . you know how you have your favourite song that you just play over and over again?" Swift said to the audience before Lopez appeared.
"You just blast it in your room and sing in front of your mirror into a hairbrush. You had that one favourite song that was your favourite to dance to. Los Angeles, this is my hairbrush song."
Lopez then appeared on stage to huge cheers from the audience before singing her 2002 hit.
Here’s a video of the duet:
