Megastar Amitabh Bachchan has hosted game show "Kaun Banega Crorepati" (KBC) five times but he still finds it nerve-wracking

Except for the third edition, which was hosted by superstar Shah Rukh Khan, Amitabh has been seen on the quizmaster's seat. He has also shot three to four episodes of the seventh season of the show based on international quiz show "Who Wants To Be A Millionaire". But the 70-year-old says he still feels nervous.

"I do get nervous. Whether it is a press meet or work. It's nerve-wracking. I disagree that just because you are a professional you are not going to get nervous, " Amitabh told reporters here during press conference held for launch of seventh season of KBC.

Before KBC's recordings started earlier this week, Bachchan had even twitted about feeling jitters in stomach.

The game show will be aired three times a week starting Sep 6
