Duchess of Cambridge, Kate Middleton, will be switching her role from being the subject of news stories to working behind-the-scenes as she will become guest editor at Huffington Post UK for one day next month.

The Duchess’ mission will be to raise awareness for mental health issues within young people, and she will enlist some leaders in the field to contribute.

"The Duchess of Cambridge has made the mental health of children a key focus of her work in recent years,” Kensington Palace said in a statement about her upcoming role as guest editor, ABC News reports.

During children's mental health week last year, Duchess Kate appeared in a PSA to shine a light on this important cause. In the video, she said, "The stigma around mental health means that they do not get the help they so badly need. This needs to change."

The Duchess has more free time since her oldest, Prince George, started nursery school earlier this month.
