Megastar Amitabh Bachchan's extended family on micro-blogging site Twitter is expanding rapidly and has reached another milestone - it crossed the three million mark Friday.

"3 MILLION FOLLOWERS!!! Holy Mother of Jesus and the Almighty! This is quite unbelievable! Thank you my TwFmXt (Twitter extended family), " tweeted the 69-year-old.

The veteran actor, who has been entertaining Bollywood buffs since over four decades, remains connected to his worldwide fans through the online medium -- his blog and Twitter, and even through his voice blog.
