When asked if she was excited for the Duke and Duchess of Sussex's baby, she responded, "Absolutely!"
They added that Windsor was a special place for The Duke and Duchess of Sussex, who also formed a part of the decision to make the move.
"They're doing well, thank you", she shared.
The friendship between royal sisters-in-law, the Duchess of Cambridge and the Duchess of Sussex, has been called into question following an alleged feud about a bridesmaid fitting for Meghan and Harry's wedding in May 2018.

A spokesperson for the company released an official statement through Us Weekly that says: 'An unprecedented amount of bets on Meghan Markle and Prince Harry to have twins forced us to stop taking any more bets on the market altogether.
'The truth is that they have both just grown up.
Meghan Markle reportedly left Kate in tears before the Royal Wedding.
