The single was first confirmed by band members Tom Fletcher and Dougie Poynter in a web chat on the group's official website, SuperCity.
McFly released the single on 7 March as a physical and downloadable track, however with Dougie Poynter entering rehab for depression and drug and alcohol abuse, the band conducted little promotion for the song.
Robert Copsey from Digital Spy awarded it 4 stars and said that: "Thankfully, there's no need for us to be knocking down the doors at Sats HQ, for the track itself offers a full and feasible explanation.
[3] Glasswerk described the song as "a departure from the electronic sound and sublime synths featured on previous singles 'Shine A Light' and 'Party Girl'.
A string orchestra accompanies the band's heartfelt lyrics about honesty and working through problems in relationships, whilst the anthemic chorus has already proved to be a huge fan's favourite at McFly's recent live shows."
McFly performed That's the Truth twice without Dougie Poynter as he was in rehab for depression and alcohol and drug problems.
