Amitabh plays 'grandpa' to Aaradhya and AbRam, as 'son' Shah Rukh attends birthday bash

Amitabh Bachchan might be the superstar of the millenium for his fans, but at the age of 75, he has turned into an adorable grandfather. The actor tweeted out some candid pictures from granddaughter Aaradhya's 6th birthday celebrations. 

While the photographers were kept busy outside the venue, there were several high profile guests attending the celebrations, including Shah Rukh Khan's four-year old son AbRam, and Aamir Khan's son Azad Rao Khan. 

Amitabh certainly seems to be enjoying the role of a grandfather. He shared a picture of himself buying little AbRam a candy floss at the party. The actor wrote 'And as for this little bundle .. he wanted the fluffy 'buddhi ka baal' cone .. so we took him to the stall made one for him and the joy of getting it is just priceless .. Abram, jr Shahrukh .. delectable !!'

Even Shah Rukh Khan was taken by the actor's simplicity, and tweeted that AbRam actually idenitifies the senior actor as Khan's father. Shah Rukh wrote 'Thank u sir. This is a moment he will always cherish. By the way he thinks u r my ‘papa’ when he sees u on TV. ' 

The entire Bachchan family was celebrating Aaradhya birthday over the weekend. Amitabh even shared a picture of Jaya Bachchan spending a sweet moment with her little grand daughter.
