Dua Lipa is not one to guess at things. In fact, the walked into the office of her future manager while still in her teens and told him matter-of-factly that she wanted to be as big as Madonna – is very much a planner, a what-to-eat-where list-maker, a time-with-each-friend scheduler and someone who makes diaries... nervous.

And so ask her how many days she has been able to spend in her new flat over the past year-and-a-half and she doesn’t guess, but tells you that she recently totalled up the exact amount.

“I did! I was actually thinking about this the other day. I moved into my flat in March last year and I counted up the days that I’ve been home and it’s been exactly two months in total – days here and there. So, no, it’s not very much.”

In fact, she admits, she’s away so often she forgets what key opens the door. “Every time! Every time I put the wrong key in.” They even have markings on them, she says – front door, flat door, clearly labelled. “But I still somehow mess that up.”

This, you suppose, is the price you pay when, from a standing start, you become one of the biggest stars on the planet, having honed a very specific brand of Rihanna-meets-Lily Allen “dark pop” – aka the screw-you floor-filler.
