Fifth Harmony: 'In every possible way you can think of – we’ve changed'

Girl group Fifth Harmony are enjoying a fast rise to fame and they have revealed that so much has changed for them in the past couple of years.

Speaking to Hit The Floor, Camila Cabello admitted that she and the girls have grown and changed 'tremendously' since they were put together on 'X Factor USA':

"The growth as individuals and as a group has been tremendous. I think since then, we’ve been through so much, so many obstacles and things we’ve had to face as a group. We’ve had to talk it out and get over it and it has made us so much stronger because of where that bond has come from."

The beauty, who just confirmed that she has split from singer Austin Mahone after just a few weeks of dating, went onto add that they're also more confident and self-assured now, which is reflected in their new material:

"As individuals we’ve all become more confident and more comfortable with ourselves. The music has changed too, from the 'Better Together EP' to the new album 'Reflection' the sound has changed; we’re dancing more, it’s a lot more urban so I think in every possible way you can think of – we’ve changed."
