Sheena, daughter of veteran filmmaker Ramesh Sippy, is nowadays travelling with the Bachchans for their world concert 'Unforgettable' - only to click photographs of the show and to compile them into a book.

Sheena is a professional photographer and has done assignments with personalities like Amitabh Bachchan, Aishwarya Rai, Imran Khan, Naomi Campbell and Zakir Husain.

Amitabh regularly posts pictures of the event on his blog with detailed captions and says Sheena is not too happy with this.

'The demand for the photographs of the shows is increasing. I am compiling some more pictures. But this is not being received well by the photographer (Sheena) since she has been assigned to do a book on the tour. She feels all her work is going out to the world before time, ' he posted on his blog site www.bigb.bigadda.com

Big B is all praise for Sheena. He wrote on his blog: 'The magnificence of the arena and the enthusiasm of the crowds are so beautifully captured by Sheena Sippy Kapoor, who has been assigned to do a book on the tour.'

Sheena is married to Shashi Kapoor's son Kunal. Her family's association with the Bachchan's dates back to the time when her father had directed Amitabh in blockbuster 'Sholay'.

Thereafter, even her brother Rohan Sippy teamed up with Abhishek in 'Bluffmaster'.

Now, she is busy capturing the special moments of the family.

To this, Amitabh stated: 'We are indeed such an integrated fraternity and proud of it.'
