Isha 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 her husband Anand — the founder of very successful Piramal Realty — since childhood.

Isha is the daughter of Mukesh Ambani, chairman of energy giant Reliance Industries. Her father’s most recent net worth was listed at US$47.3 billion.

The wedding was held at Antilla, the 27-storey Mumbai apartment building which Mr Ambani built to serve as his family home.

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.

But week-long pre-wedding ceremonies took place at a variety of five-star hotels in Udaipur, including the 18th-century City Palace pictured above.

Some high profile guests were in attendance at these pre-wedding celebrations, including former US Secretary of State, Hillary Clinton.

She and the other invited guests enjoyed discos, brunches and other activities in the northwestern city of Udaipur, Rajasthan, before moving on to the big day in Mumbai.

Beyoncé was booked to give the bride and groom a private concert at the start of their pre-wedding ceremonies, 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).

Besides former politicians, the guest list included some pretty high-profile attendees. Newly married Nick Jonas and Priyanka Chopra showed up.

So did Shah Rukh khan; Deepika Padukone and her new hubby, Ranveer Singh; Bollywood royalty Amitabh Bachan; and Aishwarya Rai.

Other reported VIP wedding guests included former Huffington Post editor-in-chief Arianna Huffington, 21st Century Fox CEO James Murdoch, and Russian supermodel Natalia Vodianova.

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.

Beyoncé reportedly made $4,000,000 during her appearance alone!
