The 42-year-old model is planning a huge party in India for Doronin's milestone and will fly Ross to Jodhpur, Rajasthan to sing for their A-list guests, reported Daily Mail online.
Campbell has put together a four-day celebration for her boyfriend and reportedly emailed guests invitations that include an image of Doronin posing underwater with a Seabob, a hand-held propulsion device - in a James Bond style photo-shoot.
"Naomi is flying a lot of people out to India and paying for everything," a source said.
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.
"No expense has been spared. Naomi's team is even helping their friends secure visas. It will be the party of the century," the source added.
