Duchess Meghan might have been only days out from giving birth, but she was still business as usual till the very end.
Indeed, in a new revelation, it has emerged that Meghan wrote a letter to some very important people which was received by the recipients just a day before she gave birth.
As the 37-year-old prepared to welcome her first child, her old high school class were celebrating their 20-year reunion - something that Meghan unfortunately had to miss out on.
But she still ensured her involvement in the event, writing a sweet note to her fellow class members to send her regards.
The letter, which was revealed by a former classmate on DailyMailTV was reported to be written on an official Kensington Palace letterhead.
A classmate revealed to the publication: "They were so excited to get that letter from her. She is remembered as someone who is very thoughtful, and to get that kind of attention now that she is a Royal went down really well."
The friend added that while the class was "disappointed" to not catch up with the now royal, they were "super excited about her giving birth to the first British-American prince, it was all anyone talked about."
Meghan gave birth to baby Archie on May 6 - just a day after the school reunion occurred.
The classmate said they hoped Meghan would be in attendance at the 25 year anniversary - when baby Archie will be a five year old!

Meghan attended Immaculate Heart High School & Middle School in LA, a private Catholic college for women.
The now-Duchess left the school in 1999 before reviving a bachelor's degree in theatre and international studies at Northwestern University School of Communication.
Meghan's old high school shared a sweet picture of a flower on Twitter to wish their former student congratulations on the birth of their son, writing: "Immaculate Heart High School & Middle School congratulates IH alumna Meghan Markle, the Duchess of Sussex, and her husband, Prince Harry, on the birth of their son."
It continued: "The school community extends best wishes of happiness to the Royal Family on this joyous event!"
