Chartered jets arriving in Udaipur for Indian heiress Isha Ambani's wedding contributed to a four-fold increase in flight traffic at the city's airport Saturday. The next day, celebrity guests were treated to an intimate private concert by Beyoncé.And that's just the pre-party.

The most lavish Indian wedding of the year is underway in the northwestern state of Rajasthan, as 27-year-old Isha Ambani -- daughter of the country's wealthiest man -- prepares to tie the knot with businessman Anand Piramal.

The pair won't officially wed until a Wednesday ceremony at the bride's family residence in Mumbai. But celebrations kicked off over the weekend at Udaipur's City Palace, a grand 16th-century complex overlooking Lake Pichola.

The bride's father Mukesh Ambani, chair of the multinational conglomerate Reliance Industries, is worth more than $47 billion, according to Forbes. And the family appears to have spared no expense putting on a show for Bollywood A-listers, business magnates, politicians and sports stars.
The guest list included advertising tycoon Martin Sorrell, cricket legend Sachin Tendulkar and the businesswoman and author Arianna Huffington. Hillary Clinton, a long-time friend of the Ambani family, was also in attendance.

Guests were able download a custom app to help stay abreast of the schedule, which is expected to include feasts, rituals and entertainment events. Chief among these was the "sangeet," a night of music and dance traditionally hosted by the bride's family. Descending on the exclusive Oberoi Udaivilas Hotel on Saturday night, a star-studded crowd witnessed performances from various musicians and Bollywood icons.

Ambani currently sits on the boards of two companies within her father's business empire. Her 33-year-old husband-to-be also hails from a powerful family, serving as executive director of Piramal Group, a sprawling conglomerate with business interests spanning healthcare, manufacturing and real estate.
