Guitarist Michael Clifford first opened up about the third album and the upcoming single in an interview with
Billboard in December 2017. He admitted: "We're at a point now where we're almost ready to put out our first single," as he promised that fans could expect it "really, really early in the new year". On 16 February 2018, the band posted a black and white picture featuring all members on Twitter, captioning it "Behind The Scenes 2018." They shared another tweet with the hashtag "#5SOS3ISCOMING" shortly afterwards, hinting at new releases. They also teased a few lyrics from the song and posted a GIF which says "We Want You Back". The song was officially announced on 19 February 2018, along with its release date, cover art, and a brief audio snippet. The song was released alongside the announcement of their worldwide promotional
5SOS III Tour dates. Drummer Ashton Irwin said of the song in an interview with
Beats 1: "'Want You Back' articulates the band we were, we are now, and what we're gonna be, that's why I like it and that's why we picked it. We also made it with close friends like we've got Andrew Goldstein who we literally see every week. We party together, we confess our sorrows and happiness. We speak to this man ." The band told
news.com.au that they are "super nervous" about the comeback song which will introduce their third album. ==Critical reception==
