Bollywood actors, Saif Ali Khan and Kareena Kapoor's doted son, Taimur Ali Khan has learnt to speak his first words. An apparently happy father, Saif Ali Khan said that Taimur is now calling him 'Abba' and he says 'gum' when he sees chewing gum. He has already learnt to say 'baby.' The media simply waits on the adorable Khan heir, to record everything new about him. They were witness to his first steps, which he took at Christmas lunch last year.
