Whilst prepping to release their single 'Hottest Girl in the World' on October 21 as the lead track from their fourth studio album Evolution, JLS have released a behind-the-scenes footage of the music video.
''We wrote this song about three months ago now and, the track, we want it to (represent) the new sound of our album really,'' explained band member Marvin Humes.
''It’s definitely a bit harder, it's a bit more R&B and the beats are heavier,'' added the 27-year-old.
The British boy band will release their new LP Evolution on November 5, and previously said that the record ''felt right,'' something that's not really surprising considering the video for their latest track has already passed the 1 million view mark on YouTube!
''We're very excited about and this is the album we wanted to make, we wanted to make this for our fans,'' said JLS.
''We didn't go by any kind of guildelines or anything like that, we just made what felt right and we're really excited about it!''
Evolution sees JLS transition in a more urban direction, and sees the four-piece group team up with a stellar list of prominent urban producers, including hip hop producers The Runners, Midi Mafia, as well as legendary R&B hitmaker Rodney Jerkins.
