Hillary Clinton and Huma Abedin headed overseas this weekend, travelling to India for a wedding hosted by the country's richest family.

The former Secretary of State and her aide are attending a five-day celebration that will end with the marriage ceremony of Isha Ambani, the 27-year-old daughter of Mukesh Ambani.

It was revealed just last week that Mukesh is the 19th richest man in the world, with a fortune of $43.4 billion thanks to his role as head of the Indian oil and gas giant Reliance Industries.

He also has close ties to The Clinton Foundation, having donated hundreds of thousands of dollars to the non-profit and worked with the couple on developing clean energy initiatives in his country.

Video of Hillary arriving at the wedding in Udpair emerged over the weekend, with the family flying guests in themselves on private planes.

Once she landed it was Clinton who was presented with flowers by the parents of the bride, with video showing the moment a giant bougquet of lillies.

Clinton then handed that bouquet off to Abedin, who was apparently on the clock for this trip.

The bride later shared a photo of herself and Clinton while out enjoying the Swadesh Bazaar with her mother.

Abedin could be seen lurking in the background of that photo.

Then it was time for the Beyone concert, which Clinton attended in a long gold dress.

She even took time to pose with the mother of the pop star, Tina Knowles.

It was a brief trip for Clinton however, who did not stick around for the wedding on Wednesday and was instead seen jetting out of the country on Monday.

The Clintons and the Ambanis have an association that goes back more than 18 years and have met several times both in India and abroad, according to Indian media reports.

Then President Bill Clinton held meetings in India with the Ambanis, including deceased founder and Mukesh's father Dhirubhai Ambani, just before and after he left the presidency in 2000-2001.

In March this year, when Hillary Clinton visited India to deliver a keynote speech at a conference in Mumbai, she dined with the Ambanis at their 27-floor Antilia residence - one of the world's most expensive homes, according to local media.

Many other top industrialists, politicians, sports and Bollywood stars descended in Udaipur on Saturday to join what has been dubbed locally "the big, fat Indian wedding."

Indian steel magnate Lakshmi Mittal, Maharashtra Chief Minister Devendra Fadnavis, cricket legend Sachin Tendulkar and newly-weds, actress Priyanka Chopra and singer Nick Jonas were among the guests joining the bash.

Former head of advertising giant WPP, Martin Sorrell, BP Group CEO Bob Dudley, Huffington Post founder Arianna Huffington, 21st Century Fox CEO James Murdoch and Saudi Energy Minister Khalid Al-Falih are also invited.

Guests for the celebrations, which will bring together two of India's most influential families, have access to an app mapping out the activities, which include a private concert by Beyonce.

Many in India, where millions live in dire poverty, have closely followed the preparations, including the Ivy League-graduate couple's engagement at the luxury Villa D'Este hotel on Italy's Lake Como, attended by more than 600 guests, and featuring a private performance by singer John Legend

This is just the latest mega-donor wedding Clinton has attended, having stopped by a number of nuptial ceremonies over the summer.

Abedin meanwhile has emerged form hiding after not being seen with her boss for months.

The pair were both spotted last Thursday for the premiere of the Network, the adaptation of the Oscar-winning film starring Bryan Cranston.

Clinton and Abedin sat side-by-side in the theater but were careful not to be photographed together while entering or leaving the Belasco Theater.

Abedin, outfitted in a $2750 Michael Kors coat, was later seen posing with Tony Goldwyn and Josh Charles at the afterparty while Clinton greeted gospel singer Bebe Winnans with a big hug.

Clinton was not spotted at the play or in India with her husband Bill, who she had been with just a few days earlier at the funeral of George H.W. Bush.

The two frequently attend the theater together, and just kicked off a speaking tour last month, which is set to resume in April.

The former president has been keeping a low profile however in the wake of his former mistress Monica Lewinsky finally speaking out about their affair in the A&E docuseries The Clinton Affair.
