The whole Bachchan family is associated with some or the other social networking site except Jaya Bachchan. Hence daughter-in-law Aishwarya Rai has taken upon herself to convince her mom-in-law to join the micro-blogging site Twitter. “A big hello from maa, I am insisting her 2 join Twitter,” Aishwarya posted on her Twitter account. While Aishwarya and her actor husband Abhishek are regulars on Twitter, Amitabh Bachchan is an active blogger.
