Kate Middleton is reportedly preparing for her new editing job in Huffington Post U.K. The 34-year-old Duchess of Cambridge will be the publication's "guest editor" on Feb. 17.

As previously reported, Duchess Kate was stepping up her efforts in raising mental health awareness for the youth. So, as part of the Duchess' editorial stint this month, she will also enlist the help of several leading figures in the mental health field to contribute to the issue.

"The Duchess of Cambridge will continue her work to highlight the importance of children's mental health when she serves as Guest Editor of @huffpostuk for a day in mid-February," the Kensington Palace wrote on Instagram. "The Duchess will use the opportunity to highlight the inspiring work being done by parents, teachers, researchers, and mental health professionals around the country."

Apart from her latest editing role, Kate Middleton is also set to attend several royal engagements and activities in the coming months. On Feb. 7, Prince William's wife is set to attend her first official event as Honorary Air Commandant of the Royal Air Force Air Cadets during the Air Force organization's 75th anniversary.

Duchess Kate will also participate in her first TV interview after her engagement with Prince William, E! News noted. The TV interview with a provisional title, "The Queen at Ninety," is reportedly part of a special documentary in honor of Queen Elizabeth II.

The Duchess, however, will not be the only member of the royal family who will participate in the TV documentary. Her husband Prince William, father-in-law Prince Charles and Camilla Parker-Bowles are reportedly joining her.

"The Queen at Ninety" is set to premiere on ITV in May, shortly after her birthday on April 21.

Speaking of the Queen, Parade revealed that she is set to pass on several royal responsibilities to younger members of the royal family as her 90th birthday looms. And according to HuffPost Living Canada, the Queen will be handing over her All England Lawn Tennis and Croquet Club patronage to Duchess Kate, after the 64 years in the position.

Prince Harry, on the other hand, will be receiving the patronage of the Rugby Football Union.

Meanwhile, royal watchers are eager to know the reason behind why Duchess Kate and Prince William ditched the Middletons' annual Mustique holiday. Hello! magazine cited the royal couple might be reluctant to let Prince George skip his new nursery routine.

The magazine also added that the Duke of Cambridge's royal commitments, which is keeping him in the U.K., might also be one of the reasons for their absence, not to mention Duchess Kate's royal engagements too.

There are also rumors circulating that Duchess Kate's absence during her family's Mustique holiday was due to her third pregnancy. However, those claims have remained as mere speculations.

In other news, the royal couple is also scheduled to embark on their first official overseas tour (since 2014) in India in the spring.
