It turns out the Sussexes' ties with some members of the royal family are stronger than others - and it may be because they have some things in common, including their plans for their children.
The source went on to say that it was "lovely that Eugenie is having her baby as Harry and Meghan are having theirs".
"They are very close. And they are all deciding to go their own route."
Eugenie and her husband Jack, whom she married in October 2018, took to Instagram to thank royal fans for their well wishes after the birth of August.
"Thank you for so many wonderful messages. Our hearts are full of love for this little human, words can't express. We are excited to be able to share these photos with you," she wrote alongside some adorable snaps of her baby boy.
"Thank you to the wonderful essential workers including our midwife who came to discharge our boy."
Baby August is great-grandchild number nine for Queen Elizabeth, 94, and Prince Philip, 99. He's also the first grandchild for Eugenie's parents Prince Andrew and Sarah Ferguson.
It's expected that August will not get a royal title and will instead be known as Master August Brooksbank.
Meghan and Harry announced their pregnancy on Valentine's Day with a sweet black and white photo taken by their friend Misan Harriman.
"We can confirm that Archie is going to be a big brother. The Duke and Duchess of Sussex are overjoyed to be expecting their second child," a spokesperson for the couple told Fox News.
The Sussexes welcomed their first child Archie Harrison Mountbatten-Windsor in May 2019.
