The youngest son of Mukesh Ambani, Asia’s richest man, married his long-time girlfriend early Saturday in what many dubbed the wedding of the year, attended by global celebrities, business tycoons and politicians, highlighting the billionaire’s staggering wealth and rising clout.

The wedding rituals, including exchanging garlands by the couple and walking around the sacred fire, began Friday and were completed past midnight.

The celebrations of Anant Ambani marrying Radhika Merchant took place at the Ambani-owned Jio World Convention Centre in Mumbai and the family home. The marriage culminated months of wedding events that featured performances by pop stars including Rihanna and Justin Bieber.

Prime Minister Narendra Modi attended a reception organized by the Ambanis on Saturday evening.

The Ambanis hosted a “blessing ceremony’’ for friends and family members to meet the couple and wish them a happy married life.

India Today television news channel reported that the newlyweds touched Modi’s feet as a show of respect and sought his blessings.

The four-day wedding celebrations began Friday with the traditional Hindu wedding ceremony and will be followed by a grand reception to run through the weekend. The guest list includes former British Prime Ministers Tony Blair and Boris Johnson; John Kerry, the former U.S. special envoy for climate, Saudi Aramco CEO Amin H. Nasser; and Adele, Lana Del Rey, Drake and David Beckham, according to local media. The Ambani family did not confirm the guest list.

Television news channels showed the arrivals of celebrities like Kim Kardashian, who was dressed in red, and professional wrestler and Hollywood actor John Cena.

Kardashian sisters Kim and Khloé took a ride in a motorized rickshaw through bustling Mumbai streets Friday before joining the wedding ceremonies, the Press Trust of India news agency said.

International guests wore traditional clothes by major Indian fashion designers. They put on embroidered sherwanis – long-sleeved outer coats worn by men in South Asia. Cena came in a sky-blue sherwani and white pants. Nick Jonas wore a pink sherwani and white pants.

Bollywood icons Amitabh Bachchan, Shah Rukh Khan, Salman Khan and Ranbir Kapoor attended the wedding and danced to popular Hindi movie songs. Indian cricketers, including icons Sachin Tendulkar, Mahendra Singh Dhoni, Jasprit Bumrah, Hardik Pandya and Suryakumar Yadav, were among the invitees.

Police imposed traffic diversions around the wedding venue from Friday to Monday to handle the influx of guests who flew to Mumbai, where heavy monsoon rains have caused flooding and flight disruptions for the past week.

The extravaganza and the display of opulence that comes with the wedding have led many to raise questions about rising inequality in India, where the gap between rich and poor is growing. The event has also sparked anger among some Mumbai residents, who say they are struggling with snarled traffic.

“It affects our earnings. I don’t care much about the wedding,” said Vikram, a taxi driver who uses only one name.

The father of the groom, Mukesh Ambani, is the world’s ninth-richest man, with a net worth of $116 billion, according to Forbes. He is the richest person in Asia. His Reliance Industries is a conglomerate reporting over $100 billion in annual revenue, with interests that include petrochemicals, oil and gas, telecoms and retail.

The Ambani family owns, among other assets, a 27-story family compound in Mumbai worth $1 billion. The building contains three helipads, a 160-car garage and a private movie theatre.

The groom, 29-year-old Anant, oversees the conglomerate’s renewable and green energy expansion. He also runs a 3,000-acre (about 1,200-hectare) animal rescue centre in Gujarat state’s Jamnagar, the family’s hometown.

The bride, Radhika Merchant, also 29, is the daughter of pharmaceutical tycoon Viren Merchant and is the marketing director for his company, Encore Healthcare, according to Vogue.

Ambani’s critics say his company has relied on political connections during Congress Party-led governments in the 1970s and ’80s, and under Prime Minister Narendra Modi’s rule after 2014.

The Ambani family’s pre-wedding celebrations have been lavish and star-studded from the start.

In March, they threw a three-day pre-nuptial bash for Anant that had 1,200 guests, including former world leaders, tech tycoons and Bollywood megastars, and performances by Rihanna, Akon and Diljit Dosanjh, a Punjabi singer who shot to international fame when he performed at Coachella. The event was also attended by tech billionaires Mark Zuckerberg and Bill Gates.

It was the start of lavish, months-long pre-wedding celebrations that grabbed headlines and set off a social media frenzy.

In May, the family took guests on a three-day cruise from Italy to France, which included Katy Perry singing her hit song “Firework” and a performance by Pitbull, according to media reports.

The family also organized a mass wedding for more than 50 underprivileged couples on July 2 as part of the celebrations.

Last week, Justin Bieber performed for hundreds of guests at a pre-wedding concert that included performances by Bollywood stars Alia Bhatt, Ranveer Singh and Salman Khan.

Ambani also made headlines in 2018, when Beyoncé performed at pre-wedding festivities for his daughter. Former U.S. Secretaries of State Hillary Clinton and John Kerry were among those who rubbed shoulders with Indian celebrities and Bollywood stars in the western Indian city of Udaipur.
