A garland-wearing Mark Zuckerberg arrives for a glitzy Indian wedding celebration — and boy is he in full vacation mode

• Mark Zuckerberg and his wife Priscilla are attending the lavish Ambani pre-wedding party in India.
• The Meta CEO appears to be in full vacation mode after being pictured with a floral garland.
• The event for Anant Ambani and Radhika Merchant is due to feature a performance by Rihanna.

Mark Zuckerberg has touched down in India for one of the most lavish pre-wedding celebrations. 

He appears to be in full vacation mode after flying in with his wife for the Ambani family's extravagant three-day affair.

The Meta CEO was pictured wearing a floral garland and sunglasses as he arrived in Gujarat on Thursday along with a grey t-shirt and red Nikes. 

The world's 11th-richest person, Mukesh Ambani, is holding the pre-wedding blowout celebration this weekend for his son Anant. He's marrying Radhika Merchant, the daughter of Encore Healthcare CEO Viren Merchant, in July. 

In 2018, the Ambanis gained global attention by hosting one of the most extravagant wedding celebrations ever for Isha Ambani and Anand Piramal.

That bash featured a private Beyoncé concert and a guest list boasting celebrities such as Priyanka Chopra, Nick Jonas, Hillary Clinton, and Arianna Huffington.

Fast forward to this weekend, and the Ambani family is once again making headlines with a grand celebration for Anant, the youngest son of Mukesh and his wife Nita.

The 1,200-strong guest list includes the likes of Bill Gates and Ivanka Trump, as well as cricketers, Bollywood stars and many other celebs.

Zuckerberg later posted a photo on Instagram of him and his wife dressed up for the occasion. By then he'd swapped his casual attire for a black suit with a dragonfly embellishment.

Billionaire investor Larry Fink, BP CEO Murray Auchincloss, and Ivanka Trump were also pictured arriving for the first day of celebrations on Friday.

Reports from The Times of India also mention that figures including Alphabet CEO Sundar Pichai and Samsung Electronics executive chair Jay Y. Lee will be attending.

Reuters reported that Rihanna would perform at the event on Friday. India Today shared a video of a rehearsal performance that seems to be the pop star singing her hit "Diamonds."

It's quite a coup considering that apart from her Super Bowl performance last year, Rihanna hasn't played live since the Abu Dhabi Grand Prix in 2016. A fee rumored to be close to eight figures might have helped convince her, however.
