Amitabh Bachchan’s emotional note on his grandson’s graduation!

Star kid Agastya is the son of Big B's daughter Shweta, who also shared numerous snapshots from the graduation ceremony and tagged Sevenoaks in London.

"In the blink of an eye. Congratulations Gus, you made it," Shweta wrote with one photo, and she captioned another photo, "Journey wisely".

Amitabh Bachchan was emotional about the moments.

On his blog, he wrote: "Another (grandchild) several miles away graduates and it's a moment of great pride and joy... The family is all with him and there are frequent messages and pictures flying about. But I mean, he was just born the other day and we had all been around his mother at Breach Candy Hospital, and carried him into the world with affection and love... And there he is today, spanking big boy, carnation on his suit lapel, hair flushed back and looking very British... And taller than everyone else in the family.”

"Err...almost... still have to see where he measures against Abhishek and me," added the actor, who towers at 6 ft-plus.
