MUMBAI: Bollywood star and former Miss World Aishwarya Rai Bachchan has put her latest film on hold due to her pregnancy, its producers said on Tuesday.

“At this point nothing is more important than Aishwarya's well-being and good health,” UTV Motion Pictures, which is making the drama “Heroine”, said in an emailed statement.

“In that context, we have all mutually agreed that the best step would be to avoid shooting further, rather than proceeding with an incredibly demanding schedule over the coming months.”

News of the 37-year-old's pregnancy was announced last week when the actress' father-in-law, Bollywood screen legend Amitabh Bachchan, expressed his excitement at becoming a grandfather on Twitter and his blog.

Aishwarya Rai Bachchan, who won the Miss World title in 1994, is married to Bachchan's 35-year-old actor son, Abhishek.

The former model, who has starred in more than 40 Indian movies, had been at the Cannes Film Festival with UTV chief executive Ronnie Screwvala in May to promote “Heroine”.

Indian media reports had speculated that she might be replaced in the lead role after her pregnancy was revealed.
