Taylor Swift walks across the stage and explains to the audience, “Now, I don’t know about you, but when I was really little… You know how you have your favourite song? That you would just play over and over again in your room, just blast it in your room, and you’d sing in front of your mirror – into a hairbrush right?”. The audience start sensing there could be a special guest and start cheering as Taylor concludes, “Los Angeles, this is my hairbrush song”. Jennifer Lopez appears on a platform at the back of the stage and the duo put on a special live performance of “Jenny From The Block” in a full circle moment for Taylor Swift as she sings alongside her Idol.
