This is not the first time the pair have worked together as Harris previously remixed Kelis' single "4th of July (Fireworks)
" in 2010. Despite their previous collaboration, Harris expressed surprise that the American songstress agreed to guest on this tune. He told The Daily Star
: "When I wrote 'Bounce' I wanted a female voice. I thought about getting Kelis but then thought, 'Nah, she'll never do it. But after a few phone calls I was amazed that she said yes."
