A little under a month ago, Duchess Catherine welcomed her third child Prince Louis of Cambridge.
Holding onto that pregnancy glow, the royal mum has made her first post-birth debut.
Prince William's wife has officially arrived at Prince Harry and Meghan Markle's royal wedding ...
And as expected, she looks absolutely phenomenal.
The mum-of-three wore a beautiful cream coat teamed with nude heels and the prettiest floral headpiece...
Truly fit for a future queen.
As predicted Prince Louis, who arrived on April 23, is too young to attend the royal wedding.
While the four-week-old stayed at home, his big brother and big sister Prince George and Princess Charlotte, have starring roles for the big day.
The youngsters are a part of the bridal party and we can't wait to watch their adorable antics unfold.
Today, Duchess Catherine will get to enjoy the celebrations as a VIP guest and has no official role during Harry and Meghan's nuptials.
Explaining the reason why, royal expert Marlene Koenig revealed to Town & Country: "[Kate] is the future queen consort when William becomes king after his father, and would unlikely be an attending person to another royal bride."
But just like she did at her little sister Pippa Middleton's wedding, Kate was on hand to help keep the little one's in line.
