"Karisma has given birth to a baby boy. The delivery took place in the morning," the hospital source told.
The actress, who gave many hits in her career including "Raja Hindustani", "Hero No.1" and "Dil Toh Pagal Hai", also has a six-year-old daughter Samaira.
Karisma's friend, jewellery designer Farah Khan Ali, wished her on her Twiiter page. "Karisma Kapoor just gave birth to a beautiful baby boy. Many congratulations to her and her family," Farah wrote.
