Oprah has come to her defence, saying that she has a good heart.
"I feel that if people really knew her that would know that she is not only everything we perceive in being graceful and dynamic in holding that position, but she just has a wonderful, warm, giving and loving heart."
Oprah added that the Duchess of Sussex does not read anything said about her.
"I think that's remarkable that despite everything that's going on she does not read anything."
The series with Prince Harry revolves around mental issues, which Oprah says she hopes will help remove stigmas around it.
