Katy Perry new track Walking on Air.

Pop star Katy Perry has released the latest song ‘Walking on air’ from her upcoming third album Prism.
The 28-year-old's third studio album will be out on October 22, 2013.
‘Walking on air’ is yet another stylistic change for the singer in relation to her previous two tracks from the album. The new song will take on the elements of club music.The new song was produced by Klas Ahlund, who has worked with Robyn, Madonna, Vanessa Hudgens and more in the past.We also think she’s alluding to John, 35, in the happy, upbeat song, when she sings, “Heaven is jealous of our love.” So this is what Katy’s pop heaven feels like — and we love it!
