In May 2014, Scott decided he wanted to get involved in the 2014 FIFA World Cup by making a football song better than the official World Cup song by Pitbull, Jennifer Lopez and Claudia Leitte. To do this, he enlisted the help of Australian pop rock band 5 Seconds of Summer, and Scott performed a rap on the song. "Hearts Upon Our Sleeve (Feat. Scott Mills)" premiered on Monday 2 June 2014, and was available for a short time as a free download at the Radio 1 website. The song gained airplay abroad, in both Australia and the United States of America, albeit without recognition for Mills. Former co-host and sports reader Chappers returned on 30 May 2014 under the guise of "90s music expert" to judge Scott's single, and promote the 2014 FIFA World Cup coverage on the BBC.
