Megastar Amitabh Bachchan has asked his fans not to follow a fake account in his name on micro-blogging website Twitter.

A "fake" user by the account name of @SrBachchanc has been re-tweeting the 72-year-old's posts to its 13,800 followers.

"CAUTION: @SrBachchanc...notice the 'c' added .. this is a FAKE account, not done by me... please refrain from communicating to it," Big B tweeted via his official Twitter handle @SrBachchan on Sunday.

Amitabh, who has close to 15 million followers on Twitter, is mostly seen active on it by keeping his fans updated about his day-to-day schedules.

He will next be seen with Farhan Akhtar in "Wazir".
