Amitabh and Perry were among the star performers at the opening ceremony of the fifth edition of the Indian Premier League (IPL) in Chennai Tuesday night.
"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.
It was Perry’s maiden performance in the country, and she chose to go desi for her performance. She wore a blingy choli teamed with pink-coloured transparent lowers, and accessorised her look with a maang tika and bindis on her forehead.
Big B, who recited a poem at the ceremony, says he didn’t know about the 27-year-old pop icon earlier.
"I would probably get killed for this, but I had not heard of her till last night. The age difference is playing havoc," he added.
The actor, who is a fan of evergreen and classic music by British rock band ‘The Beatles’, feels "today’s grandchildren would ‘snuff’ at that".
