India's richest man is bringing Rihanna and 1,200 guests to a pre-wedding bash for his son

NEW DELHI (AP) — It could be the biggest party this small west Indian city has ever seen. As billionaire industrialist Mukesh Ambani prepares for the wedding of his young son this summer, he's expecting billionaires from around the world, heads of state, and Hollywood and Bollywood royalty to attend a three-day bash in the family's hometown, starting Friday.

They'll be entertained by pop superstar Rihanna, magician David Blaine and famous Bollywood singers.

The party is in Jamnagar, a city of around 600,000 in a near-desert part of Gujarat state. It's the family's hometown, and the home of the main oil refinery of their business empire, Reliance Industries. There will also be traditional ceremonies in a temple complex.
