It would have been nice if Big B had let Abhishek and Aishwarya announce the good news in their own way and whenever they felt ready to share it -- talk about stealing their thunder!!
Why the media is doing the publicity? Is it a paid news or the channel is owned by Bachhan's family? It is natural that a married girl will become a mother one day. At 37, Ash will become mother after 4 yrs of her marriage. Was there any problem? Big B should tweet about that also.
