Former US secretary of state Hillary Clinton and a host of Bollywood's biggest names were among guests as the daughter of India's richest man got married.
Mukesh Ambani's daughter Isha, 27, married Anand Piramal, the 33-year-old son of another multi-billionaire, Ajay Piramal, on Wednesday in a traditional ceremony in Mumbai.
The marriage brings together two of India's most influential families.
Mukesh Ambani, who is worth $43bn (£34bn) according to Forbes magazine, is the chairman of Reliance Industries, which owns businesses in energy, textiles and telecommunications firms.
Ajay Piramal, who is worth $4bn (£3bn) according to Forbes, is the chairman of Piramal Enterprises, which has interests in pharma, healthcare and financial services.
The wedding took place at the Ambanis' 27-storey billion-dollar home in Mumbai, which is known as one of the most expensive homes in the world.
The structure was draped in red roses and lit up with lights for the occasion.
According to India's Filmfare magazine, 600 people were expected at the event, which has been dubbed "the big, fat Indian wedding".
It comes after international pop star Beyonce was hired to perform at an elaborate pre-wedding bash in Udaipur, Rajasthan, in the lead up to the big day.
Video soon emerged on social media appearing to show Mrs Clinton and another former US secretary of state, John Kerry, dancing with Indian actor Shah Rukh Khan.
Bloomberg previously reported that the wedding was expected to cost up to $100m (£79.8m), while someone close to the family said it would cost no more than $15m (£12m).
Not everyone on social media was in awe of the lavish festivities, though, with some saying the money could have been used to "single-handedly eradicate poverty in India".
Despite being one of the world's fastest growing economies, one in five Indians – 270 million people – live in poverty, according to 2012 figures from the World Bank. Latest figures put the country's total population at 1.3 billion.
