Originally, "Yo-Yo" was set to be Roberts' debut single, but "Beat of My Drum" was selected in its place.  "Beat of My Drum" and "Lucky Day", Roberts' previous singles, garnered positive comments from critics, but failed to impact commercially.  "Yo-Yo" was written by Roberts, Maya Von Doll and Dimitri Tikovoi while it was produced by latter, and was the first song to be composed by the group.  Roberts also claimed the track had defined her musical style.

Cinderella's Eyes: Cinderella's Eyes is the debut studio album by English recording artist Nicola Roberts.  A member of the British girl group Girls Aloud, Roberts drew inspiration from her time with the group.  Her experience with Girls Aloud's formation found her being labelled "ugly" by the media, and the constant negative attention and subsequent personal problems resulted in her struggling with her confidence.  She started recording for the album in 2010 and co-wrote all of the original tracks on the album, working closely with producers Dimitri Tikovoi, Maya von Doll (from electro group Sohodolls) and Diplo on the album, as well as Canadian electropop band Dragonette.  The concept of the album derived from fairy tales, focusing mostly upon "Cinderella" after titling the album "Cinderella's Eyes".  The album artwork features Roberts next to a collection of vintage artefacts wearing a modern interpretation of the Cinderella glass slipper, co-produced by shoe designer Atalanta Weller.
