The wealthy son of the Aga Khan, Prince Rahim Aga Khan celebrated his recent wedding to American supermodel Kendra Spears in lavish fashion at Manhattan’s Museum of Natural History on Saturday night.

Guests including Naomi Campbell, who introduced the couple at a party, Leonardo DiCaprio, Red Hot Chili Peppers frontman Anthony Kiedis, actors Edward Norton and Rashida Jones toasted the prince and his beautiful bride.

Also there partying until the early hours under the Central Park West museum’s famous 94-foot-long fiberglass replica of a blue whale, were billionaires Ron Burkle, Vivi Nevo, Oscar-winning producer and director Brian Grazer and Prince Vincent of Liechtenstein, as well as a host of top models, including Karlie Kloss, who are close friends with the bride.

The 250 guests were treated to performances by British rockers Band of Skulls and American indie band the Yeah Yeah Yeahs.

One guest told us, “It was a very elegant event with a very well-heeled and dressed crowd, many who had flown in from London, Paris and Milan. There were a lot of models there who were friends with the bride, who wore a beautiful white gown.”

In a tale fit for Hollywood, the eldest son of Aga Khan IV and one of the 10 richest royals in the world (worth an estimated $800 million) married Seattle-born model Spears, 25, now rechristened Princess Salwa Aga Khan, on Aug. 31 in a Muslim ceremony at a palace in Geneva, Switzerland.

The 41-year-old prince is the heir to the title and fortune of Aga Khan IV, who is the Imam of Shia Ismaili Muslims and is considered a descendant of Prophet Muhammad.

Spears is a regular on the catwalks of Paris and Milan. She was touted as the “next Cindy Crawford” after launching her career in 2008 and became a face of Escada, Prada, Diane von Furstenberg and other top brands.

The American beauty will fit right into the family. Prince Rahim’s younger brother, Prince Hussain, married American model Kristin White, while his father was married to British model Sarah Croker-Poole. And Rahim’s grandfather was married to Rita Hayworth.
