Many of Mulroney’s friends were quick to praise the mother-of-three, including her husband, fellow stylist Ben, who wrote, “Proud of you, honey.”
The news comes after her BFF, the Duchess of Sussex, made headlines this week for guest editing Vogue’s iconic September issue.
Meghan is the first person to guest edit the magazine's September issue in 103 years, and it isn't a role she took lightly.
As part of her collaboration with editor-in-chief Edward Enninful, Meghan picked out 15 trailblazing women to feature on the cover.
She also decided to include the poem “A Note from the Beach” by Matt Haig.
Although the piece is all about body positivity, it features a very unexpected swear word.
In her introduction, the 37-year-old wrote: "A personal favourite and the best reminder during the summer season…or any season, as a matter of fact."
The poem begins: “Hello. I am the beach.
“I am created by waves and currents. I was made of eroded rocks. I exist next to the sea. I have been around for millions of years. I was around at the dawn of life itself.”
It continues: “And I have to tell you something. I don’t care about your body.
“I am a beach. I literally don’t give a f—.”
