Infamous Middleton siblings, Kate and Pippa, have been making headlines this week. However, what was remarkably interesting was the report suggesting who has a much better writing abilities between the two sisters.

Earlier this week, reports emerged that Duchess Kate will join The Huffington Post UK for a day as its "guest editor" in February. She will take the helm commissioning content to raise mental awareness for the youth as well as to invite leading mental health professionals around the nation to contribute to the issue, as per Kensington Palace's announcement on Instagram.

The 34-year-old Duchess, however, is not the first Middleton sibling to venture into writing and journalism. As a matter of fact, Inquisitr noted that Pippa Middleton also had a stint as a freelance writer. She even published her own book called "Celebrate: A Year of British Festivities for Families and Friends" in 2012.

Unfortunately, reviewers weren't impressed with Pippa's writing skills. Inquisitr's Tim Butters even wrote that, "if there's a book that needed burning," it was Pippa's book "Celebrate."

"'Celebrate' really is banal beyond belief and seen by many at the time as merely an excuse for Pippa to cash in on her royal connections and create a shocking literary crime in the process," Butters wrote.

Pippa, however, wasn't deterred by her book's failure. In fact, she took a job at Daily Telegraph as a celebrity columnist. However, her career on the publication ended just six months after because of poor reader reaction. She also had a stint at the Spectator before she went missing in action.

With Kate's upcoming editing work, royal watchers can't help but wonder who among the Middleton siblings have better literary abilities. However, writing must run in the Middletons' bloodlines since their mom Carole had also written party-planning columns for two publications last year.

Meanwhile, Pippa's 40-year-old millionaire boyfriend, James Matthews, has been rumored to raise some eyebrows in the royal circles. The reason? Matthews' toxic playboy brother and "Made in Chelsea" star Spencer.

In a recent Daily Mail report, the publication detailed Spencer's "voracious womanizing" lifestyle, wherein he has slept with no fewer than 1,000 women. The 27-year-old brother of Pippa's boyfriend wrote his relentless pursuit of the opposite sex and bed-hopping journey in his autobiography entitled "Confessions of a Chelsea Boy," which was published in 2014.

Despite having a controversial brother and the snobbery in the royal circles, James seemed to have captured the heart of one of Britain's most eligible young woman, Pippa. In fact, they're already living together after just two months of dating.

In other news, the Palace has recently announced Kate and Prince Harry's official outings. People reported that the Duchess will be at London's St. Clement Danes Church on Feb. 7 to mark the 75th anniversary of the Royal Air Force Cadets.

Harry, on the other hand, will be supporting wounded warriors who will join the British team in his Paralympic-style Invictus Game in Orlando in May. The 31-year-old royal will also visit Bath on Jan. 29 to see the team trials, which are helmed by the veterans' charity Help for Heroes with support from the government's Ministry of Defense and The Royal British Legion.

Speaking of Harry, his rumored ladylove Princess Maria-Olympia of Greece and Denmark was recently spotted in London on Wednesday. The 20-year-old New York University student was seen running some errands with a blonde female friend. She is expected back in New York when the spring semester starts on Monday, Daily Mail revealed.
