According to the TOI, Sanjay Dutt and Manyata are expecting a baby boy in December 2010.
Manyata has lately not been accompanying Dutt during his travels and public appearances, something that she used to do earlier. She has reportedly been advised complete rest by doctors.
Meanwhile, Sanjay has been visiting shrines to pay obeisance to the deities.
In April, he visited two temples and the Ajmer Sharif Dargah in Jaipur.
Dutt married his long time girlfriend Manyata at the Taj Exotica in Goa on February 7, 2008. Later on Feb 11 the couple got married according to Hindu rites at the house of Pradeep, a mutual friend in Varsova, Mumbai.
Dutt had married twice earlier - with Richa Sharma from 1987 to 1996 and with Rhea Pillai from 1998 to 2005.
Richa Sharma died of cancer in 1996. The couple had a daughter, Trishala, who was born in 1988 and is now in the US.
Dutt's marriage with Rhea ended in a divorce.
Dutt is all set to start work on his first independently produced film. Yet to be titled, the film will be helmed by David Dhawan and feature Dutt and Ajay Devgan in the lead.
He is leaving for Oman, Mozambique and other places to scout for locales and is expected to be away from Mumbai for 25 days.
