The song was written and produced by Lukasz "Dr. Luke" Gottwald, with additional writing by Sheppard Solomon.

The single made number 12 on the US Billboard Hot Dance Club Play chart.

The music video for "Nothing in This World" was shot by Scott Speer in Los Angeles on September 5 and 6, 2006, in South Pasadena and Long Beach Polytechnic High School, California.

In this video, Hilton parodies teen flick The Girl Next Door with her own mock movie trailer in which she plays a sexy starlet loved and adored by an incessantly teased, teenage neighbour (played by Nick Lane).

Elisha Cuthbert, the original Girl star, makes a cameo and also with an early appearance of actor/model Scott Elrod as the boyfriend.
