Excited about the news, Edward shared the accomplishment on #TBT.
On Thursday evening, Meghan also shared another intimate moment from this historic edition and posted a behind-the-scenes video from the shoot in London.
"I was like, 'Lovely to meet you, Duchess, '" Enninful recalled in the video.
"And that's what I feel really proud that we've accomplished", Meghan said, before she picked up some fun celebratory, glitter hats for both her Enninful to wear to commemorate their success.
It is reported that Meghan's guest-edited issue became the United Kingdom fashion magazine's fastest-selling in its history and its top seller of the past decade.
Meghan went on to reveal she had a "surprise" for Enninful, to congratulate him for bringing her vision to life. And maybe I could push it just a little bit more and see if you would be willing to let me guest edit. "Then you were like, 'Call me Meghan!'" Which caused the two to laugh.
Today, thanks to British Vogue Editor-in-chief Edward Enninful, we are now aware that the issue the Duchess guest edited has been crowned the fastest-selling issue in the magazine's recent history!
"I didn't know if anyone had ever done it before". "You have an editor's eye, I mean, I've never seen anything like it".
Enninful praised Meghan for being "so thorough from beginning to end".
In said video, Markle and Enninful call some of the women who ended up on the issue's cover, including Laverne Cox, Adwoa Aboah, Yara Shahidi (the "very first name" Markle had in mind for the cover), and Jane Fonda.
Actress turned activist Jane Fonda said in her call: "Meghan, I'm so proud of you for using your awesome platform and strong voice, and I'm so honoured to be part of it with those other incredible women".
"From January to now, how much we've been working on this, and to just say yes, you'd help me on Smart Works - unbelievable".
The "Forces for Change" issue featured a number of empowering women including environmental campaigner Greta Thunberg and former U.S. first lady Michelle Obama.
A second said: "Love this, love her so much". "She wanted, instead, to focus on the women she admires", he explained of Meghan.
