One thing I thought was really weird as far as their friendship went, when they did the Come dine with Little Mix and it seemed like they'd never been to one another's houses . Specifically Leigh's anyway, cus she gave them all a tour. I think the friendship aspect of the group hasn't been there for a lot longer than we realise. Friendly work colleagues who care about each other, sure. But if they were to split up I really don't think they'd stay in contact
