The Duchess of Sussex is "saddened" by a report she faced a bullying complaint during her time at Kensington Palace, her spokesman has said.
The Times newspaper says Meghan allegedly drove two personal assistants out of the household and undermined the confidence of a third member of staff.
Meghan's spokesman said it was the "latest attack on her character".
It comes before Meghan and Prince Harry's TV interview with Oprah Winfrey is due to be aired in the UK on Monday.
The duchess lived at Kensington Palace for nearly a year after her marriage to Prince Harry in May 2018.
According to the story in the Times, the complaint was made in October 2018.
Buckingham Palace, which is responsible for the hiring of royal staff, has not commented on the report. Kensington Palace has been contacted for a comment.
A statement issued by Meghan's spokesman said: "The duchess is saddened by this latest attack on her character, particularly as someone who has been the target of bullying herself and is deeply committed to supporting those who have experienced pain and trauma.
"She is determined to continue her work building compassion around the world and will keep striving to set an example for doing what is right and doing what is good."
Palace staff have for some time itched to get their side of the story out; some feel that they went out of their way to help Meghan after the wedding only to be treated rudely or later dismissed as uncaring or worse.
