Amitabh Bachchan on Thursday tweeted images from a recording session where he is seen collaborating with son Abhishek, daughter-in-law Aishwarya and granddaughter Aaradhya. 

In one image, he poses with Aaradhya, with a mic in front of them, and in another picture Aaradhya's parents Abhishek and Aishwarya look excited about their daughter recording with Big B. 

"When granddaughter and grandfather get in front of the mic in the Studio and make music," Big B wrote while sharing the picture.

In one image, the Bachchans are seen smiling for the camera with Big B flashing a victory sign. Aaradhya looks ready to record wearing headphones.

Big B also posted a family picture from the recording room. 

"And the celebrations begin... but for what... its just another day another year... big deal ! Better off making music with the family," he tweeted.
