The 41-year-old supermodel and Nikolai Von Bismark - who she has been romantically linked with amidst rumours her marriage to Jamie Hince is on the rocks - recently spent 10 days on the Caribbean island and now look to be more frequent visitors after splashing out on a year-long lease for a villa in Toucan Hill.

A source told the Daily Star newspaper: "This is a clear signal the relationship has moved up a gear into something permanent and serious."

The hilltop property boasts four bedrooms, two infinity pools and seven acres of grounds, and the British beauty - who has a 13-year-old daughter, Lila, with ex-boyfriend Jefferson Hack - wants the villa to be a family getaway.

The source added: "Kate wants her daughter and Nikolai's mother Debbie to be able to join them on the island so it made sense to rent it for the next year and keep their options open.

It was recently claimed Nikolai, 28, has secretly been living in Kate's London home.

A source said: "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.

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