The band will release 'Taking Over Me' as their second single on July 29, ahead of their debut album later this year.
The accompanying music video sees the four-piece embark on a road trip down the West Coast of America, before performing their new single in the desert.
Talking about the video to Digital Spy, Joel Peat joked: "We get girls in the video for this, by the way. Not just Andy! We all got a piece of the pie."
Andy Brown added: "We have a big party at the end and then we do a big performance scene in the desert, so it's going to be awesome."
'Taking Over Me' serves as the official follow-up to 'When She Was Mine', which reached number four on the UK chart earlier this year.
