Prince Harry and Meghan share sweet message for Prince Louis on his first birthday

April is certainly a busy month of celebrations for the royal family, with Prince Harry and Meghan Markle's baby expected to arrive any day now, and the Queen having celebrated her 93rd birthday on Easter Sunday.

And of course, today (23rd April), marks the birthday of another very special royal, little Prince Louis, who has just turned one.

The Duke and Duchess of Cambridge late last night released three adorable photos of their youngest son to mark the special occasion, and it’s the first glimpse we’ve had of Louis since his christening back in the summer.

The sweet pictures were taken by Catherine herself, at the family’s country home, Anmer Hall, in Norfolk, and show Prince George and Princess Charlotte’s brother having a whale of a time playing in the countryside gardens.

William and Catherine also shared the images on social media, and over on Instagram, Louis’ auntie and uncle, the Duke and Duchess of Sussex, were keen to share their well-wishes for their little nephew.

Meghan and Harry commented on one of the photos, to wish Prince Louis a happy birthday with an adorable message.

Commenting from their official @sussexroyal account, they wrote, ‘Happy Birthday Louis! Sending lots of love from both of us 🎂🎈xo’. How lovely!

The comment comes after rising speculation that Meghan is actually the one in charge of the Duke and Duchess’s Instagram account, with many royal fans noticing the captions being written with American spellings and in a tone they’ve come to expect from the Duchess herself.

Normally, royal social media accounts are run by the royal communications team, so it would certainly be a break from the norm if true.

It is thought to be just days until Meghan welcomes her first child with Prince Harry.

According to multiple reports, her mother Doria Ragland has just jetted into the UK from LA, sparking excitement that the birth is imminent.

Royal fans were also left on tenterhooks over the weekend, as a report from the Sunday Times claimed that the Duke and Duchess were planning a move to Africa after their baby is born, in order to carry out their Commonwealth work over there.

So far, Buckingham Palace have responded that no plans are set in stone as of yet, although some royal reporters are stating that rather than a permanent move abroad, Harry and Meghan could spend months at a time out in Africa to work, before returning to their Windsor base for the rest of the year.
