Amitabh Bachchan is not only India's oldest Megastar, but also the biggest craze on social media. On Twitter alone, he has a mind-blowing 28 million number of followers. "This is just the love and affection of well wishers .. thank you all .. NEXT 30 MILLION !! hehe," he tweeted

The second biggest 'shahenshah' on Twitter is Shah Rukh Khan, who commands about 26.30 million followers, while 'Badshah' Salman Khan has about 24.10 million of them. On the other hand, Aamir Khan trails them with 21.40 million followers.

Recently, AR Rahman crossed the magic 15 million number on the micro-blogging site.

These numbers are unthinkable for Southern stars, whose popularity is restricted to a part of India.
