New Delhi, Dec 10 (IANS): Bollywood couple Aamir Khan and Kiran Rao have named their newborn son Azad Rao Khan after scholar and freedom fighter Maulana Abul Kalam Azad, Aamir's "great grand uncle".

"Hey guys, most excited to share with y'all that we have finally chosen a name for our baby boy...Azad. Azad Rao Khan. I left the final choice to Kiran, and she has named him after my great grand uncle Maulana Azad, the great freedom fighter, whom the family is most proud of," Aamir revealed on social networking site Facebook.

"Azad means free or liberated. We want to thank everyone for their warm wishes and blessings, and needless to say we are absolutely overjoyed and feel most blessed. Much love," added the actor-producer.

Aamir-Kiran's son was born Dec 1 through IVF to a surrogate mother at a private clinic in Mumbai. The couple resorted to IVF due to medical complications.

This is Kiran's first baby, but Aamir has a son, Junaid, and a daughter, Ira, from his first wife Reena.

Aamir ended his 15-year-old marriage with Reena in 2002, and during the shooting of Ashutosh Gowariker's "Lagaan", he and the film's assistant director Kiran ended up together.

They tied the knot in 2005.

In 2009, Kiran got pregnant, but she had a miscarriage. However, the duo now feel "blessed" with the newborn.
