The youngest son of Asia's richest man is getting married, and the pre-wedding event features Rihanna, a 9-page dress code, and live animals

On Wednesday, Ambani and his bride-to-be hosted a communal dinner for 51,000 local residents in Gujarat, The Hindu reported.

The event took place in the Jogwad village, near the Reliance Township in Jamnagar, The Hindu reported.

According to the outlet, serving food to the community during auspicious family occasions has long been a tradition of the Ambanis.

Rihanna took to the stage barefoot to perform in a lime green and pink local-inspired outfit at the pre-wedding event on Friday night.

She performed 19 songs, including hits such as "Umbrella," "Diamonds," and "Work," NME reported.

"I'm here tonight in honor of Anant and Radhika. Thank you for having me here. God bless your union. I wish you all the best. Congratulations," she said to the couple, who at one point joined her on stage.

As she departed from Jamnagar airport, Rihanna told reporters: "The show was the best. I haven't done a real show in eight years."

Reports estimate that the singer had been paid between $6 and $9 million for her performance.

Rihanna had previously been spotted arriving in Jamnagar with ASAP Rocky. In the clip, she can be seen exiting a building and getting onto a cart.

A fan also uploaded an Instagram video of multiple wooden crates being transported out of an airport arrival hall, with the caption, "Rihanna's luggage has arrived in India."

"What she bring with her? A folding house?" one comment under the post said, to which Rihanna responded, "The stage couldn't fit in my carryon."

The Ambanis have had megastars perform at weddings before.

In 2018 Beyoncé performed at Isha Ambani and Anand Piramal's pre-wedding ceremony. Isha Ambani is the family patriarch's only daughter.

In 2019, Coldplay's front man, Chris Martin, and The Chainsmokers entertained guests attending Akash Ambani — the soon-to-be-wed Ambani's older brother — and Shloka Mehta's pre-wedding bash in Switzerland. The couple also had Adam Levine serenade them at their post-wedding bash.

Some of the world's most rich and famous have been pictured at the bash, including Ivanka Trump and Mark Zuckerberg.

The extensive guest list for the weekend includes celebrities, billionaires, and tech leaders such as Bill Gates and Sundar Pichai.

Disney CEO Bob Iger is also likely to be on the list of invitees, Reuters reported.

Reliance Industries and Disney announced an $8.5 billion merger of their India TV and streaming media assets earlier this week.

According to an event itinerary obtained by The Times, there will be a cocktail party on the first day.

Video published on social media shows the ornate venue festooned in flowers and brimming full of A-list guests, who were treated to a drone show in the night sky.

On the second day, guests will be taken to the Reliance animal rescue center for "a walk on the wild side," The Times said. The center is the groom's pet project.

In the evening, guests will attend a "mela rouge," The Times added. "Mela" can refer to a fair or a festival.

The last day includes a "tusker trails" event where guests can spend the afternoon "surrounded by the wonders of nature" — including over 200 elephants, 300 big cats, and 120 reptiles previously at risk of being sold or poached, per The Times.

On top of the nine-page dress code, hair stylists and makeup artists will also be available for guests, The Times reported.

The dress code includes a "jungle fever" theme and "comfortable shoes" for the visit to the animal rescue center on the second day, and "dazzling" Indian outfits for the mela, per The Times.

At the end of February, Reliance Foundation shared a video on its official YouTube channel showcasing the construction progress of the temples.

In the video, the founder and chairperson of Reliance Foundation, Nita Ambani — the Ambani patriarch's wife and mother to his three children — can be seen speaking with various worshippers and the artists involved in designing the temples.
