Granddaughter Navya wants Katy Perry's autograph, Big B

All run after Amitabh Bachchan's autograph but the megastar of Bollywood is trying his level best to get pop singer Katy Perry’s autograph as his granddaughter Navya Naveli is an ardent fan of Katy and she wants her autograph.

Katy Perry 27 performed at the IPL opening ceremony along with other stars in Chennai.

"The granddaughter has a fancy for the singer Katy Perry. I hope I have the name correct. Yes just checked, it is right... Navya wants her autograph for she loves her. So efforts are on to make that happen," the 69-year-old posted on his blog

The 69-year-old actor said he did not have the idea who Katy was before this show and reminisced his days of listening to Beatles.

"I would probably get killed for this, but I had not heard of her till last night. The age difference is playing havoc!," he said.

"In hospital a friend gave me an entire collection of songs, some unprinted too, of the Beatles. Bet today's grandchildren would 'snuff' at that, but for us it was like possessing a Bible ?"

Well, Amitabh is trying hard to fulfill the demand of his granddaughter.
