Steps reformed in May 2011 for a four-part documentary series on Sky Living titled Steps: Reunion. The series started airing on 28 September, following an announcement of a second greatest hits album, The Ultimate Collection, that was released on 10 October 2011. The album entered the charts at number one, becoming the band's third album to achieve this feat. The second series of Steps: Reunion titled "Steps: On the Road Again" aired on Sky Living in April 2012; the series followed the band as they embarked on their sellout 22-date UK tour. On 24 September 2012, the group confirmed they would release their fourth studio album Light Up The World on 12 November 2012, alongside a six-date Christmas tour, starting from 30 November and ending on 5 December. The group reformed for a second time on 1 January 2017 in celebration of their 20th anniversary, and later announced their fifth studio album Tears on the Dancefloor, which was released in April 2017 and entered the charts at number 2. On 5 March 2017, the group confirmed the release of the new album, alongside its lead single, "Scared of the Dark", and a 22-date tour, Party on the Dancefloor. A deluxe edition of the album, titled Tears on the Dancefloor: Crying at the Disco, was released on 27 October.
