At 4 a.m. on Wednesday, Nov. 16, 2011, Aishwarya Rai developed labor pains and six hours later delivered a healthy baby girl at the Seven Hills Hospital in Mumbai.

Aishwarya's father-in-law, Amitabh Bachchan, was not far behind in expressing his joy at becoming a grand father to the world, and tweeted: "I AM DADA to the cutest baby girl, A dada ji ... Ecstatic."

According to the Seven Hills Hospital sources, the delivery was normal and came a few minutes before 10 a.m. Both the Bachchan and Rai families were present at the hospital to welcome the (already) Star Baby.

Three rooms on the fifth floor of the hospital were booked for this occasion -- one for Aishwarya, the mother to be, one for the Bachchan family and the third for the Rai family. This entire floor was kept off limits for all general public and hospital staff.
