According to News.com.au Meghan also wrote about Kate on her blog, The Tig, the same year the photo was taken.
"Grown women seem to retain this childhood fantasy. Just look at the pomp and circumstance surrounding the royal wedding and endless conversation about Princess Kate," the now-wife of Prince Harry wrote.
Despite shutting down the blog after joining the royal family, Meghan remains passionate about writing and all things editorial.
Recently, the Duchess of Sussex made history as the first person in 103 years to guest edit British Vogue's September issue.
The theme of the issue was "Forces for CHANGE," as part of Meghan's decision to showcase impactful people in the cover.

According to the Sussex Royals Instagram, "the Duchess chose a diverse selection of women from all walks of life, each driving impact and raising the bar for equality, kindness, justice and open-mindedness."
Meghan didn't feature on the cover herself, which Edward Enninful - the editor-in-chief of Vogue - said was deliberate because she thought it would be "a ‘boastful’ thing to do for this particular project.
"She wanted, instead, to focus on the women she admires."
At the time, the Duchess of Sussex also said "Guest Editing the September issue of British Vogue has been rewarding, educational and inspiring," and thanked her friends for "lending their time and energy to help within these pages and on the cover."
