Over five decades, she starred in more than 150 films, including classics like Mr India, Chandni, ChaalBaaz and Sadma.

She was considered one of the very few Indian female superstars capable of huge box office success without the support of a male hero.

From the age of four, she had worked in films in the Tamil, Telugu, Malayalam, Kannada and Hindi languages.

The actress was in the United Arab Emirates to attend the wedding of her nephew, Mohit Marwah.

Sridevi's husband Boney Kapoor and daughter Khushi were with her when she passed away on Saturday, reports say.
