Family members confirmed to the Indian Express website that the actress had passed away on Saturday morning while attending a family wedding.

Born Shree Amma Yanger Ayyapan in the southern Indian state of Tamil Nadu, Sridevi started acting at the age of four with a role in the Tamil language film, Thunaivan.

The actress made her Bollywooddebut in 1979 with "Solva Sawan" (16th spring), but she made her mark in the Hindi film industry with the film "Sadma" (Shock).
