'Worth It' hitmakers Fifth Harmony have opened up about their highly anticipated second studio album and hinted that it'll have a more mature and soulful sound. 

During an interview with Billboard, songstress Lauren Jauregui confessed that the new album is very much a work in progress and 5H won't make fans wait too long before they unveil new music:

"Don’t worry! 5H2 is coming! You’ll have music to soothe your soul soon, everything will be fine, we love you to death and we’re not going anywhere. I promise.”

“It’s a really good vibe for recording — [Max Martin] is in a great spirit the whole time. We’ve been wanting to work with Max for a while, and his camp as well. They’ve produced some of the best records of all time, year after year, consistently. They’re so talented and creative, and there’s real camaraderie and positivity.”

Jauregui went onto add that the lyrics will be more grown-up this time around and the style will reflect their changing tastes:

“For starters, we definitely want to mature in terms of our lyrics and content. Although [on the first album] we touched upon a bunch of subjects that we definitely agreed with and our very relevant to us, like girl power and self-love, hopefully this time around we can have some more vulnerability, some more ballads and mid-tempo type [songs], to balance out this album. We want you to sit through it and feel a roller coaster of emotions."
