Harry and Meghan quit the monarchy in March following months of negotiations about their new roles and promptly moved to Canada, before relocating again to Los Angeles, US.
Their move meant being largely cut off from the royal family, all of whom are self-isolating at royal residences in the UK.
But now the whole family are expected to reunite virtually for a very special occasion; Archie Mountbatten-Windsor's first birthday on May 6.
"The Queen will wish him happy birthday this week via Zoom as will the Cambridge children," Katie Nicholl told OK! Magazine.
"They haven't seen their little cousin in months so they've been looking forward to seeing how much he's grown."
It's understood Harry and Meghan may have been planning to return to the UK to mark the special day, but the coronavirus pandemic would have put an end to any such plans.
Instead, they'll connect with the rest of the royal family using video calls, which the royals have all become familiar with while carrying out duties in isolation.
"The hope had been that Archie's first birthday would somehow be marked with some members of the Royal Family, cousins, grandparents and some godparents in the UK when they were over," Royal biographer Penny Junor told Express.
"Now they are cut off from family it is hard for everybody. On the day they will no doubt make many calls to family."
Prior to Harry and Meghan's royal exit there were rumours of tensions between them and the Duke and Duchess of Cambridge, with many claiming the two couples were "feuding".
And though they reportedly haven't spoken in "months", Archie's birthday will undoubtedly bring the two families together from afar.
But the royals aren't the only ones who haven't seen Archie in months.
Royal fans haven't had a glimpse of 'baby Sussex' since Christmas, when his parents released a Christmas card with the bub front and centre.
Now royal fans and experts alike are sure the couple will release new photos of Archie for his birthday, potentially sharing shots of him at their new Los Angeles home.
It's understood that the Sussex had hoped to throw Archie a party there, featuring a star-studded guest list of Meghan and Harry's Hollywood A-lister friends, but the COVID-19 pandemic put an end to those plans too.
