MUMBAI - Top global celebrities will don "jungle fever" outfits in India for a trip to the zoo on Saturday as part of a party thrown by Asia's richest man.
Pop icon Rihanna, Facebook founder Mark Zuckerberg and Donald Trump's daughter Ivanka are among the rich and famous guests who jetted in for a three-day gala celebration hosted by billionaire tycoon Mukesh Ambani.
This weekend's party is an elaborate pre-wedding ceremony for younger son Anant and fiancee Radhika Merchant, the daughter of wealthy pharmaceutical moguls.
The three-day gala -- which saw "Umbrella" singer Rihanna perform on Friday for the first time since last year's Superbowl -- will continue Saturday with a trip to an "animal rescue centre" housing exotic animals.
The facility is a pet project of Anant's built in his family's hometown Jamnagar in western Gujarat state, where the weekend party is taking place.
Indian media reports said the family will on Saturday host a "Walk on the Wildside", an event held outdoors in the Ambani's animal rescue centre.
"Jungle fever" is the suggested dress code, and guests have been advised to wear comfortable shoes and clothing, reports said.
In the evening, reports added, guests will ditch their safari-themed outfits for more elegant wear for an evening party celebrating Indian culture.
Bollywood stars Amitabh Bachchan and Shah Rukh Khan, cricket icons Sachin Tendulkar and M.S. Dhoni, and industry titan Gautam Adani are also invited in a who's-who of India's super-rich.
