Little Mix have "improved" since their first album.
The chart-toppers, Perrie Edwards, Jesy Nelson, Leigh-Anne Pinnock and Jade Thirlwall - are set to release their second record, 'Salute', in November and believe they have grown as singers and songwriters since they made 'DNA' in 2012.
Jesy said: "I would just say it's a lot more mature and more R&B. It's just really cool."
Jade added: "The first album will always be special because it was our first, but I think this one is better. I think our voices have improved, I think we've improved as writers. I'm excited for people to hear it."
The 'Move' band shot to fame on 'The X Factor' in 2011 and believe fellow pop star Lady Gaga, who was a guest on the show, blessed them with good luck when they met.
Jesy added to Bliss magazine: "Lady Gaga's lovely. She's normal, really. We met her on 'The X Factor' and she says, 'I've got a gift which will bring you good luck', and she pulled a hairpin from her hair. I put it in my pocket and we won 'The X Factor!' "
