It features vocals from Florence and the Machine singer Florence Welch. Harris previously worked with the band in a remix of their single, "Spectrum" (2012). While recording 18 Months, Harris expressed interest in working with Welch. He mentioned that it was not easy and he had to chase her, due to schedule conflicts. Welch accepted his invitation and the two recorded "Sweet Nothing". The track premiered on The Chris Moyles Show on BBC Radio 1 on 28 August 2012 and was later released as the fifth single from the album on 12 October 2012.
