Those allegations later changed to focus on the fact that it was reportedly actually the royal brothers who were the ones that weren't getting along.
More recently, Ms Latham was a key figure in the 2016 Presidential campaign of Hillary Clinton where she was Chief of Staff to Campaign Manager John Podesta.
The Duke and Duchess of Sussex cut ties with the Cambridges, revealing plans last week to create their own household - but when it came to seeking total royal freedom, the answer was a resounding "no".
She says: "The idea about royal protocol and royal etiquette and royal privacy is not the same as the expectation of celebrity and Meghan, to some extent, is in that process of trying to find a process of transition between the celebrity and the royal".
They may not be the royal Fab Four of Kensington Palace anymore, but at least we'll always have the memories.
The household refers to the place that the royals have their offices in and base their staff.
Harry and Meghan are understood to have lobbied for an autonomous new court, but the Queen and the Prince of Wales, who will jointly fund their office, thought otherwise.
The couple is also in the process of moving from a cottage in the grounds of Kensington Palace, where William and Kate live, to a new home on the royal family's Windsor Estate. She also has a United Kingdom political background - she worked for the late Culture Secretary Tessa Jowell.
Kensington Palace said his new role will include "advising Their Royal Highnesses on their charitable initiatives - including work on the environment, mental health, and early childhood".
Latham will be directly reporting to the Queen's communications secretary. This will effectively split Prince Harry, the Duke of Sussex, away from his brother and heir to the throne, Prince William, the Duke of Cambridge.
The times, they are a-changin' in the British Royal Family.
