evidence: Lavish wedding celebrations for the son of Asia's richest man resumed on Saturday with a star-studded guestlist including Hollywood celebrities, global business leaders and two former British prime ministers. Billionaire tycoon Mukesh Ambani's youngest son Anant and fiancee Radhika Merchant, both 29, are tying the knot this weekend in Mumbai, India, following months of pre-marriage parties. [...] Wedding events earlier this year included a party at the Ambanis' ancestral home, where a purpose-built Hindu temple was unveiled alongside private performances by singers Rihanna and Justin Bieber.
