"Wazir" star Amitabh Bachchan has become the first Bollywood celebrity to have 19 million followers on popular micro-blogging site Twitter.

The 73-year-old megastar beaten his contemporaries Shah Rukh Khan (17.5 million), Aamir Khan (16,2 million), Salman Khan (15.8 million) and Priyanka Chopra (12.5 million) with his new milestone.
