Amitabh Bachchan, who marks his birthday today, is all set to celebrate Diwali in a grand manner. The most lavish Diwali bash of B-Town will soon be hosted by the Bachchan family. Since ages, it has almost become a tradition of sorts in Bollywood to turn up at the Bachchans’ Juhu bungalow in their festive attires and indulge in Diwali festivities. According to the industry buzz, Big B has already sent out the invites for the bash, which will be held this month. Last year, the Bachchan family celebrated Diwali with a quiet pooja at home. The family was bereaved due to the death of Shweta Bachchan Nanda’s father-in-law, Rajan Nanda, and hence there were no celebrations by the clan.
