Saif was photographed with Randhir Kapoor, and with Soha and Kunal:
Karisma and Amrita, both of whom posted messages on their Instagram accounts, were pictured exiting Breach Candy Hospital:
"The family is delighted. Taimur Ali Khan Pataudi is a beautiful baby boy and both mother and son are doing very well!!," Soha Ali Khan told news agency PTI.
A couple of months ago, Kareena Kapoor, 36, and Saif Ali Khan, 46, denied reports of a gender determination test. They also dismissed rumours that the baby would be born in London and would be named Saifeena (surely this was a joke rumour). Their chosen name for baby - Taimur - has raised some eyebrows on Twitter. Several posts have criticized the couple for having picked a name associated with Timur or Tamerlane, who invaded and destroyed Delhi in 1398.
Kareena Kapoor and Saif Ali Khan co-starred in 2006 film Omkara but they only began dating after they made Tashan in 2008. Kareena was last seen in Udta Punjab this year and will work on Veer Di Wedding after a short maternity leave. Saif, last seen in 2015 film Phantom, has the Vishal Bhardwaj-directed Rangoon out next year.
Saif Ali Khan has a daughter and a son with ex-wife Amrita Singh.
