The 41-year-old model has been letting her new beau Nikolai Von Bismarck, 28, secretly stay in the basement of her former marital home in North London in order to stop him from crossing paths with her staff or daughter Lila, 13.

A source told The Sun newspaper: "A lot of people know Kate has been seeing a lot of Nikolai, but she's never been this open. Their relationship is pretty intense and he has been virtually living at her London home, but has been staying in the basement quite a lot."

The insider added: "Nikolai has clothes at both of Kate's houses, and although he hasn't moved in permanently he seems pretty comfortable there."

The blonde stunner's rumoured new romance comes just three months after Kate split from her Kills musician husband Jamie, 46, just four years after they tied the knot.

Since their relationship broke down, Kate has been seeking solace in her ex-boyfriend Jefferson Hack, with whom she has Lila, by flying to Niagara Falls for a private holiday.

And while she knows things between her and Jamie are bad, she's hoping they can at least stay amicable, just like she has with her other former flames.
