Bollywood megastar Amitabh Bachchan says his presence at the inaugural of the Bandra-Worli sea link's extension here had created "fresh controversy" and clarifies he attended because he was invited by a minister.

"The Rajiv Gandhi Sagari Setu or the Bandra Worli Sea Link was opening up the remaining four tracks on this massive and symbolic structure that connects two regions of the suburb over the sea.

I had been invited by the Minister in the Government to attend and so I went along," Big B posted on his blog.

Amitabh Wednesday graced the event as a special guest but his presence at a Congress function after a long time led to controversy. Chief Minister Ashok Chavan insisted that he did not know Bachchan was to be the special guest.

"It was a short and sweet ceremony conducted on the road over the bridge itself and then all the dignitaries were invited to cut the ribbon a little further down the track by riding on antique, and old model cars which was an absolute delight.

"The media has been hounding me since the event at the sea link has got over through incessant SMSes and the electronic (media) has followed me even to the theatre where we were seeing Arshad' (Warsi)'s film - a fresh controversy has been rapidly manufactured on my involvement in today's event on the sea link. But of that some other time and space," he wrote.
