But she has now quit after being in the job for only about six months, according to The Sunday Times.
But of course we already knew that the Duchess of Sussex has a knack for taste.
Both the unnamed bodyguard and Ms Cohen worked for Ms Markle and her husband Prince Harry.
The Scotland Yard inspector, who is understood to be leaving the Metropolitan Police as well as her royal role, is expected to stop working at Kensington Palace very soon.
"Unlike someone who has grown up in the Royal Family and has been used to having close protection from an early age, it can be constraining", says a source.
Following the birth of their firstborn child, Meghan and Harry will move to Frogmore Cottage at Windsor Castle which is now being refurbished. Royal biographer Robert Jobson claimed in his book, Charles at Seventy, that a stressed-out Harry became "short-tempered" with staff and insisted: "What Meghan wants, she gets".
"Even though she was a famous actress, she could still do what she wanted in the way of getting around freely".
'But in her current role she can't go anywhere without her protection team and that's a massive constraining force on an individual like her'.
But despite Meghan being due to give birth to her and Harry's birthday in March or April, she and Harry are showing no signs of slowing down as they take on more engagements.
Last year Markle's personal assistant, Melissa Touabti, reportedly resigned after just six months.
After a long history of being close to the Queen as her assistant private secretary and Press spokesperson, she filled the role for Meghan temporarily before her wedding.
