Supermodel Naomi Campbell has sparked wedding rumours

Supermodel Naomi Campbell has sparked wedding rumours after booking a month long "honeymoon" with boyfriend, Russian billionaire Vladislav Doronin.

The 39-year-old model has booked a luxury holiday which will cost a whopping 1 million pounds and she is calling it a honeymoon, reported Sun online.

"The honeymoon planned to end just before Christmas, is costing close to 1 million pounds because they will only use private jets and stay at the best hotels," said a source close to the couple.

Rumours, that the English supermodel will be marrying Doronin, known as Russia's Donald Trump, have been doing the rounds ever since she moved to Russia earlier this year to set up house with the business tycoon.

The couple first met at the 2008 Cannes Film Festival and attended the star-studded A-List birthday dinner held for the legendary South African leader Nelson Mandela. Soon after, the pair became inseparable, famously vacationing on Vladislav Doronin’s yacht off St Tropez in the South of France last summer in clear view of the paparazzi.
