"We are not in the studio because we are working a lot. Next year, though, we are going to go in and co-write," says the group.
The girls revealed that having five different personalities is an asset, not a liability. "We're all so different and there's five different ideas," sys the group. "Each of us like a different genre of music, so it seeps into the decisions that we make."
They're also prepping for their upcoming tour with Demi Lovato. "To be in the same atmosphere as [her] is so awesome," says the group. "We really look up to her. She's one of our role models. When she asked us to be on tour, it was like, 'Oh my god, absolutely.'"
