Little Mix are "addicted" to each other.
The 'Salute' hitmakers can't spend enough time together and will always want to meet up even when they're not working.
Jesy Nelson said: "To be honest, we're just loving what we're doing and we get to experience all of this together, which is amazing. There aren't many people who can say they see different things every day.
"We genuinely get on so well, and even though we're in each other's pockets, we never argue - and no one believes us, but even when we get done with work for the day, we still want to have sleepovers. It's like we're addicted to each other."
And the group - which also includes Leigh-Anne Pinnock, Jade Thirlwall and Perrie Edwards - think it's important for girls to stick together because they become a "stronger force" to be reckoned with.
Jesy added to Teen Vogue magazine: "When girls stick together, we're a stronger force. When girls are bitchy, it's such a shame because there's no need for it and if girls stick together, we can take over the world."
