"Welcome to our official Instagram; we look forward to sharing the work that drives us, the causes we support, important announcements, and the opportunity to shine a light on key issues," the couple's first official post read.
"We thank you for your support, and welcome you to @sussexroyal."
Given all the drama with the royals, it is only natural that we've been waiting for Kate and Wills to respond to them leaving.
And boy did they come out swinging.
In a classic post-breakup move, the Cambridges have updated their profile photo.
Gone is the iconic photo of Meghan, Harry, Kate and William together at their first appearance as a foursome at the first annual Royal Foundation Forum in February 2018.
The Kensington Royal profile images were changed to a photo of the Cambridge family.
The photo features our favourite royal tots: Prince George, 5, Princess Charlotte, 3, and Prince Louis, who turns 1 this month.
If it looks familiar, it was their family’s Christmas card last year.
