NEW DELHI (AP) — In March, Asia’s richest man Mukesh Ambani threw a three-day prenuptial bash for his son that included a 1,200-person guest list, including former world leaders, tech tycoons and Bollywood's megastars, and a performance by renowned singer Rihanna. It was only the start of their months-long lavish pre-wedding celebrations which have grabbed headlines and set off a social media frenzy. In May, the family took guests on a 3-day pre-wedding cruise from Italy to France, which included a DJ set from David Guetta, Katy Perry belting out her hit song “Firework” and a performance by Pitbull to cap it off, according to media reports.
