Sources close to the Bachchans' family astrologer told rediff.com that the wedding will be held after the release of their new film together, Guru.
The astrologers have advised that February 19 is the ideal time for the couple to wed, as Aishwarya's celestial planetary position will become compatible.
According to sources, the wedding will be held at Mumbai's Grand Hyatt hotel in the presence of relatives and friends.
Neeta Lulla and Anna Singh will design the wedding dress for Ash and Abhishek respectively.
Amitabh Bachchan and Jaya Bhaduri too married soon after the release of Amitabh's first hit Zanjeer, in which both actors starred.
