Oprah Winfrey is to star as a brothel madam in 'Ruined'.

The television personality - who is one of the richest women in the US thanks to her huge media empire - will take the starring role of Mama Nadi in the HBO film, an adaptation of the Lynn Nottage book of the same name.

The novel tells the tale of a woman in war-torn Congo who tries to stop the women working for her from getting caught in the war between rebel armies and the country's government.

Nottage - who won a Pulitzer prize for the book - is adapting the screenplay for the project, while Oprah will produce the film.

Oprah, 56, has used her voice for a number of animated movie roles in recent years, but has not starred in a film since 1998's 'Beloved'.

She is best known as an actress for her performance in 1985's 'The Color Purple'.
