Before Miley Cyrus hits the stage at the MTV Video Music Awards, the superstar singer is giving fans a glimpse of what's to come on her upcoming album. Queen of Twerk revealed the cover art for Bangerz on Twitter When gurl goes big, she goes B.I.G.! And Katy Perry is bringing it bigger than ever for the VMAs. The fierce and fiery Katy is set to perform Roar at the end of the show, but that's just the beginning because it'll hardly be a standard performance. Katy has revealed she'll be rocking out at a secret location, and we can now tell you that location is apparently under the Brooklyn Bridge! Taylor Swift and Jennifer Lopez brought a little Bronx to Los Angeles. J.Lo was the "22" singer's surprise guest performer during the last stop of her Red Tour at L.A.'s Staple Center. The two dueted on Lopez's hit, "Jenny From the Block." Swift introduced Lopez by talking about when she was a little girl. "You know how you have your favorite song that you just play over and over and over again," she said. "You just blast it in your room and you'd sing in front of your mirror into a hairbrush, right? You have that one favorite song. It was your favorite song to dance to. Los Angeles, this is my hairbrush song."
