“Her writing brought to life so many aspects of our country and the trials and tribulations its people,” said Singh.
“We salute her for having the courage to do this.”
Singh, who produced the award-winning film of the life of the late former president Nelson Mandela, “Mandela: Long Walk To Freedom”, said he had last seen Gordimer at the premiere of the movie.
He claimed to have been honoured to have her in attendance and extended his condolences to her family.
In a statement sent on behalf of the Gordimer family, law firm Edward Nathan Sonnenbergs said Gordimer died peacefully in her sleep at her Johannesburg home on Sunday.
“Her son Hugo and daughter Oriane and her caring helpers were with her… A private memorial service will be announced at a later date,” said the law firm.
Gordimer was 90 years old.
President Jacob Zuma and Archbishop Desmond Tutu are among those who have sent messages of condolences to her family.
