After all, acting is infectious!! Shweta Bachchan Nanda marked her acting debut with dad Amitabh Bachchan for an ad-film which Big B is endorsing. Big B was sporting an old man look holding a stick in his hand whereas Shweta wore a yellow Punjabi suit. The father-daughter duo was snapped on the sets of the ad-film and Shweta was spotted giving natural expressions.

Mr. Bachchan even tweeted a still from the ad which has daughter Shweta hugging him from behind. Big B shared and captioned it ''T 2812 - Daughters be the best .. !!'' Moreover, Shweta Bachchan Nanda has never acted before and she is a columnist and is turning author with her book, Paradise Towers.

Talking about her acting fear Shweta said, ''There is something about "Start sound, camera, action" that makes me freeze up and garble my speech like I have a mouth full of marbles. Being an actor and a successful one at that, is the stuff fairy-tales are made of, as you reach unimaginable heights. But it is a tough world and most people do not realise the personal sacrifices made to get to these lofty positions. A lot of my life has been shaped by these very sacrifices made by my parents." 

Big B often writes on his blog on how she accompanies him on the sets or checks on his health while shooting.
