Move over Anna Wintour, there's a new super-chic editor in town!

Kate Middleton is to embark on a new challenge in a bid to raise awareness for children's mental health — she's set to guest edit The Huffington Post U.K. for a day in February.

The Duchess of Cambridge, 34, will take the helm at the British arm of the online news aggregator and blog, commissioning content from a range of experts, parents and teachers in order to shine the spotlight on children's mental health issues.

"The Duchess of Cambridge has made the mental health of young children a key focus of her work in recent year," a Kensington Palace spokesperson told Us Weekly on Friday, January 15. "The Duchess will be commissioning contributions from a number of leading figures in the mental health sector as well as from young people, parents and teachers. We look forward to welcoming the Huffington Post team to Kensington Palace next month."

For their part, the Huffington Post U.K. can't wait for Prince William's wife to take control for a whole day.

"We are thrilled that The Duchess of Cambridge is joining the HuffPost U.K. team for a day as a guest editor," said Stephen Hull, editor in chief of Huffington Post U.K. "Dealing with mental health issues has been a major editorial focus for us and I'm very excited to be working together on such an important project."
