Perry also revealed that two more tracks from the album will preview in September -- the hip-hop heavy "Dark Horse," featuring rapper Juicy J, on Sept. 17, and "Walking on Air” on Sept. 30. THR also learned heard that she’s set to open the American Music Awards in November. By then, a second single should be climbing the charts, although a rep for the singer will only confirm that another song is expected to go to radio by the end of the year.
But WAIT, I just realized that all of the pop girls are going to be into their new eras by the time the AMA's roll around. This might be an interesting night.
