Everything You Need to Know About Isha Ambani's Multi-Million Dollar Wedding (Beyoncé Included)

From ELLE

Beyoncé is in India this week to attend the high-profile wedding of Isha Ambani and Anand Piramal. The two are expected to wed this Wednesday, December 12 with a lavish, multi-million dollar ceremony that tops even Nick Jonas and Priyanka Chopra's estimated $800K nuptials (!!!). Here, everything we know about the extravagant celebration, from the couple's engagement to their private Beyoncé concert.

Who is the happy couple?

Ambani is the daughter of Mukesh Ambani, chairman of energy giant Reliance Industries. USA Today reports that he is the richest man in India; other reports peg him as the richest man in all of Asia. Her father's most recent net worth was listed at $47.3 billion, which puts the whole multi-million dollar celebration thing in perspective. Ambani's future father-in-law, Ajay Piramal, is chairman of the Piramal Group and estimated to be worth a cool $4.2 billion, largely from pharmaceuticals.

Ambani herself has degrees from both Yale and Stanford, and is a co-director for Reliance Jio, India's largest 4G network. She's been friends with Piramal-the founder of very successful Piramal Realty-since childhood, and Piramal proposed to Ambani in May of this year at a temple in Mahabaleshwar.

When is the wedding?

Multiple outlets report that Ambani and Piramal's wedding will take place today, December 12, following a week of pre-wedding ceremonies. Based on her Instagram account, it looks like Ambani arrived in Udaipur on Sunday to get things started.

So why has Beyoncé been in India since Sunday?

Beyoncé was booked to give the bride and groom a private concert at the start of their pre-wedding ceremonies on Sunday, where she sang “Crazy in Love,” “Naughty Girl,” and “Perfect,” among other tracks, at the Oberoi Udaivilas Hotel. By the looks of it, Beyoncé had several outfit changes during her set, including the above embellished number (by Indian designers Abu Jani and Sandeep Khosla) and the below all-gold bodysuit.

Where is the wedding?

Ambani and Piramal will tie the knot at the Ambani's residence, called Antilia, today. Their home gets its name from the mythical island featured throughout Greek and Roman mythology and has multiple helipads, 27 floors (so, a mini-skyscraper) and a staff of 600 to keep the mansion up and running-and that's on a normal, non-wedding day. Antilia is considered to be one of the most expensive mansions in the entire world, second only to London's Buckingham Palace.

How much does the wedding cost?

Bloomberg reports two figures for the lavish wedding, both in the multi-millions. Per the outlet, wedding experts estimate that once everything is said and done, the total cost of all wedding-related activities rounds out to a clean $100 million. Meanwhile, anonymous sources close to the couple tell the outlet that the Ambani family didn't spend more than $15 million on the nuptials.

That $15 million includes the cost of their actual wedding and pre-wedding ceremonies, the five 5-star hotels the family booked for their guests, more than 100 chartered flights, a rented "war room" set up in Mumbai for staff facilitating the technicalities of the wedding, and meals that the Ambani family donated to the people of Udaipur as a gratitude for hosting (enough food to feed 5,100 people three meals a day for four days).

Who else will attend?

Ambani and Piramal's guest list includes some pretty high-profile attendees. Besides Beyoncé, People reports that Hillary Clinton, Nick Jonas, Priyanka Chopra, Shah Rukh Khan, and Henry Kravis are also expected to make an appearance.
