Megastar Amitabh Bachchan today pooh-poohed the reports in a section of the press that he had been paid Rs 115 crore by server ''bigadda.com'' to write his blog.

''This in entirely incorrect. I use the services of the server bigadda.com and nothing else, there are no finances involved at all'', the Bollywood actor said.

Writing in his blog after attending the opening night of the Cannes film festival, Amitabh has challenged the Mumbai-based tabloid to show him receipts of the payment made or any contract signed by him and disclose the source that has confirmed the information to it.

Besides Amitabh, his wife Jaya, son Abhishek and daughter-in-law Aishwarya Rai Bachchan also attended the opening night function at Cannes, where the film 'Blindness' was screened.
