"We'll hopefully be moving into our new house by summer," says the 24-year-old, who looks gorgeous as she models pastel fashions in our exclusive photo shoot. "It's being extended and gutted, but as we've taken it apart there's been problems, so we've had to redo a lot of the actual structural work. We found rot, damp, mould, a lot of the old original timbers had to be replaced, as well as the windows, the roof… so I mean, it's pretty extensive work."
She and her rapper husband, real name Stephen Manderson, may be one of the most in-demand celebrity couples in the country – but, at weekends, they're just like the rest of us. "We've been spending hours at the weekends in paint shops and tile shops!" she admits.
Millie, who is also planning to install heated outdoor kennels for their pet pooches French bulldog Herby, Staffordshire bull terrier Alfie, Matilda the Doberman and Belle the Boston terrier, adds: "People keep asking if it feels really different to be married. It makes us feel like a stronger unit and it's grounding to have that security – it will be really nice when we move into our home."
