Naomi Campbell books "honeymoon"

Naomi Campbell and her boyfriend have booked their “honeymoon”.

The supermodel and Russian billionaire Vladislav Doronin have been planning the month-long, £1 million holiday for weeks. When their assistants phoned to make reservations, hotel staff were shocked to hear the trip – due to begin by the end of November - would be the couple’s “honeymoon”.

Naomi, 39, and Vladislav are not married, sparking speculation they plan to wed within the next two weeks.

The romantic trip is expected to be lavish, even by Naomi’s standards. The couple will fly by private jet and stay only in five-star luxury hotels.

It’s not the first time the pair have enjoyed a lavish romantic break. Last week, Naomi flew Vladislav to Morocco for less than 24 hours to celebrate his 47th birthday.
