The British supermodel organised a huge two-day bash in Jodhpur to mark Vladislav Doronin's 50th birthday, and famous guests were reportedly transported in 12 chartered planes.
The first party, held at the historic Mehrangarh Fort, saw attendees dress up in traditional Indian costume, and a second bash had an Art Deco theme and featured a performance by superstar singer Diana Ross.
Pictures have emerged on Twitter.com showing Campbell dressed in an elaborate feathered costume, while Moss is seen in a gold, sparkly outfit complete with 1920s-style curls.
Other guests included supermodel Karolina Kurkova, fashion designers Zac Posen and John Galliano, as well as singer Holly Valance and British royal Sarah Ferguson, Duchess of York.
Campbell has been dating the Russian billionaire, who turned 50 on Wednesday (07Nov12), since 2008.
