evidence: Mark Zuckerberg, Bill Gates and Ivanka Trump were among the high-profile international figures who jetted to India for billionaire heir Anant Ambani’s extravagant pre-wedding party, which wrapped up Sunday. [...] Ambani is the youngest son of Asia’s richest man, Mukesh Ambani, who has an estimated fortune of $117 billion, according to Forbes. The 28-year-old serves as a director at an energy business operated by Reliance, the Indian conglomerate founded by his grandfather. Although Ambani and his 29-year-old girlfriend Radhika Merchant are not due to marry until July, no expense was spared at the lavish pre-wedding bash. Guests were served 500 dishes created by around 100 chefs, according to Reuters, which saw a copy of a planning document provided to invitees.
