WATCH: Anant Ambani makes Mukesh Ambani tear up with emotional speech

Asia's richest man Mukesh Ambani broke down in tears during his son Anant Ambani's speech at his pre-wedding event in Gujarat's Jamnagar, where he discussed his health issues on Friday.

As Anant and his fiancee Radhika Merchant's three-day grand pre-wedding celebrations kicked off on Friday, the younger Ambani gave a speech thanking his family for the event, India Today reported.

The owner of Reliance Industries, an Indian multinational conglomerate, was spotted teary-eyed as his 28-year-old son spoke about his struggles with health throughout his childhood.

He said: "My family has gone all out to make me feel special. My life has not entirely been a bed of roses. I have experienced the pain of thorns. 

"I have faced many health issues since childhood, but my father and mother have never let me feel that I have suffered. They have always stood by me."

Earlier this week, Anant and Radhika began the pre-wedding festivities with a community feast, hosting thousands of people from neighbouring villages and serving them Gujarati delicacies.

Over 1,000 guests, including Bill Gates, Meta CEO Mark Zuckerberg, and Bollywood stars like Amitabh Bachchan, Shah Rukh Khan, Aamir Khan, Deepika Padukone, and Ranveer Singh, are listed as guests for the three-day event.

Pop star Rihanna also performed for the first time in India, showcasing her timeless hits like "Diamonds", "Rude Boy", and "Pour It Up".
