All eyes should have been on the models during the Rahul Mishra runway show in Paris on Monday. However, many attendees were left gazing at Isha Ambani instead thanks to her dazzling look.

The billionaire heiress seemed to steal the show, oozing confidence as she sat front row next to rapper Cardi B.

Isha stunned in a custom metallic gray strapless gown from the brand, which contained a corset bodice with intricate beading and a draped midi skirt.

The 34-year-old, who is the only daughter of India's richest man, Mukesh Ambani, and his wife, Nita, completed the look with a matching scarf and strappy heels. 

But what really ensured all eyes would be on her was her handbag.

Isha toted a Hermès Sac Bijou Birkin - an extremely rare and expensive purse that longtime fans of the designer could only dream of getting their hands on.

The bag is reportedly crafted from 18-karat white gold, adorned with 2,712 gemstones and is estimated to be worth a whopping $2 million. 

According to Elle, it is one of the rarest Hermès bags in history as only three have ever been made.

The publication said Isha borrowed it from her mother's wardrobe for the occasion. 

The bag was first released in 2012 as part of the Hermès Haute Bijouterie Collection and was conceived by Hermès Creative Director of Fine Jewelry Pierre Hardy.

Sotheby's previously reported that it was meant to 'blur the line between handbag and high jewelry.' 

As if that wasn't enough, Isha also accessorized with custom Lorraine Schwartz jewelry pieces including 40-karat white diamond earrings and a matching 40-karat necklace.

So who is the woman who stole the show at Paris Fashion Week?

Isha - whose dad runs the oil company Reliance Industries and is estimated to be worth $87 billion - has long been a strong force in the fashion world.

She often attends star-studded events - including the Met Gala - and even posed for Vogue Australia in 2017.

She graduated from Yale University in 2013 with a degree in psychology and South Asian studies. She also received her MBA from Stanford University in 2018.

She now serves as a member of the board at her father's company.

'All my life, I've seen my family dedicate themselves to growing Reliance and improving quality of life for all Indians,' she previously told Vogue Australia. 

'I feel a sense of responsibility towards the company and my country. 

'I truly believe that helping to grow Reliance is my dharma.'

'I have always known I would be involved with Reliance in some capacity. 

'My parents raised me with very traditional values, and it was ingrained in me from an early age that family should always come first. 

'I've always believed that part of my personal responsibilities towards my family extends professionally as well.'

She previously made headlines thanks to her extravagant wedding to real estate mogul Anand Piramal in 2018.

The lavish affair was believed to have cost as much as $100 million and included a private concert from Beyonce.

Attendees included Hillary Clinton, Priyanka Chopra, Nick Jonas and Bollywood superstars like Aishwarya Rai, Amitabh Bachchan and Shah Rukh Khan.

In 2022, Isha and her husband, who is the son of another billionaire, welcomed twins.
