Naseeruddin Shah and son Vivaan Shah

A Twitter handle in the name of Naseeruddin Shah has existed for almost two years. It was assumed to be the veteran star's social media profile. But son Vivaan clarified with a tweet, "Everyone please listen up. Very important. Dad is not on Twitter. It is a fake account!" Wonder what made the Happy New Year (2015) actor wake up to the fake profile so late?
