The ceremony will be held on April 20 at the Bachchan residence in Mumbai, where the country's Hindi-language film industry is based, the Times of India reported on its front page.

Calls to Rai's media manager and the Bachchan household for comment went unanswered.

"The wedding will be a small, private affair with only close family and friends in attendance, and it will be held at the Bachchans' residence," the Press Trust of India quoted an unnamed source as saying.

Rai, a leading Bollywood actress, and Bachchan, son of legendary screen icon Amitabh Bachchan, got engaged on January 14, capping months of media speculation about their relationship.

The couple have been dubbed "Abhiash," a melding of their two names in the fashion of "Brangelina" for Brad Pitt and Angelina Jolie.

Rai is widely regarded as one of the most beautiful women in the world and Bachchan, who is one of Bollywood's leading men, was voted the sexiest Asian man by a British newspaper last year.
