Big B celebrates grandson Agastya�s birthday in capital

Megastar Amitabh Bachchan was recently in the capital to celebrate his grandson Agastya Nanda�s 13th birthday.

The Shahenshah star felt nostalgic and happy as his daughter Shweta Nanda�s son turned a teenager on Saturday.

"Agastya�s birthday. Enters his �teen�. Here to wish him," Amitabh posted on Saturday night on srbachchan.tumblr.com.

While his grandson was covered in a hood, Amitabh was spotted in casuals with a jacket on.

Saturday early morning, he had posted, "He (Agastya) was just born the other day and we were all rushing from different parts of the country to the Breach Candy Hospital for the delivery."
