The actor, who became a member of the social networking site at the behest of his friend, filmmaker Karan Johar, has managed to scoop some 169,565 followers in just forty days.
But Tharoor, Minister of State for External Affairs, is way ahead of Khan with his 661,456 followers.
"In few months I am going to overtake Shahi Tharoor (on twitter). I am going for him. He is our god," Khan said at the 'NDTV Indian of the Year Awards' function here last night.
Tharoor said he will be happy to be overtakan by Khan.
"I had predicted this the day Shah Rukh joined twitter. I will be happy rather than regret it," the politician said.
The 44-year-old actor, who was honoured as the Entertainment Icon, said he joined the website after Johar's insistence.
"Karan told me that people are anyway abusing you so why don't you let them abuse you directly. I can says whatever I want to say. There are so many people who want to know about you," Khan said, adding that Amitabh Bachchan started the blogging phenomenon in Bollywood.
Bachchan, 67, said he initially wanted a website but was introduced to blog and started liking it. The megastar, however, said he will not join twitter.
