After all, the Grammy winner performed her first full concert in eight years as part of the three days pre-wedding celebrations Indian billionaire Mukesh Ambani threw for his son Anant Ambani and businesswoman Radhika Merchant.

In fact, the celebratory weekend, which wrapped Sunday March 3, featured a who's who of high-profile guests like Mark Zuckerberg, Bill Gates and Ivanka Trump, in addition to a performance by magician David Blaine.

The extravagant party, which took place in Jamnagar in the western state of Gujarat, celebrated the impending marriage between Anant and Radhika, the daughter of pharmaceutical CEO and billionaire Viren Merchant. Despite the lavish weekend, the couple did not say "I do" as their official wedding festivities are due to be held in July, according to the BBC.

The celebration welcomed around 1,200 guests from all over the world, and was so big that, per the BBC, the local airport was temporarily granted international status in order to receive the almost 130 flights that were arriving.

Mukesh, the chairman and managing director or Reliance Industries whom Forbes reported has a net worth of around $117 billion, is currently ranked as the 9th richest person in the world and the richest man in Asia.

And the family are going all out for Anant's July wedding, even building a new Hindu temple complex for the ceremony that will later be open to the public, according to CNN.

And this isn't the first time the family has taken their parties up a notch. Beyoncé performed at his daughter Isha Ambani's pre-wedding party in 2018, and Coldplay's Chris Martin and The Chainsmokers performed for his eldest son Akash Ambani's event in 2019.
