Naomi Campbell will pay Diana Ross more than $500,000 to perform at her boyfriend's 50th birthday bash.

The 42-year-old model is planning a huge party in India next week for her billionaire lover Vladislav Doronin's milestone and according to MailOnline, will fly Diana Ross to Jodhpur in Rajasthan to sing for their A list guests.

Naomi has put together a four-day celebration for her beau and reportedly emailed guests invitations that include an image of her boyfriend posing underwater with a Seabob, a hand-held propulsion device - in a James Bond style photo-shoot.

A source previously said: ''Naomi is flying a lot of people out to India and paying for everything.''

The British style icon has booked out an entire five-star hotel for the main celebrations but has planned a number of other events.

She is also said to be working with Paris-based travel expert Omar Cherif, who owns OC Travel, to arrange the luxury celebration.

Another source said: ''No expense has been spared. Naomi's team is even helping their friends secure visas. It will be the party of the century.''

The couple - who have been dating since 2008 - celebrated the model's 40th birthday together with a huge party in the south of France two years ago.

Guests including the Black Eyed Peas, Grace Jones, Donatella Versace, Kate Moss, Giorgio Armani and Jennifer Lopez helped her celebrate the milestone.
