However, the photo, a throwback from 2017, has divided fans with some people accusing the Cambridges of shading Markle, 39.

“Interesting photo selection! No Meghan…” one person commented. Another said, “The shade of them using this pic rather than one including his wife.”

“There must have been hundreds of photos you could have picked, but you chose to post one of Harry, William and Kate. I’m sure not including Meghan wasn’t unintentional. Not very classy…” someone speculated.

One person remarked that Prince Harry “was visibly so much happier in these times” adding, “Such a shame he’s been so manipulated into sidelining his family and friends.”

“Back when relationships were intact aka pre-Meghan era,” another said.

Others defended the choice to exclude Markle as unintentional.

“Most birthday posts here are of Kate, William and the birthday person, or even individual pics of the birthday person, even the Queens birthday pic didn’t include the Duke of Edinburgh: check out the others, Princess Anne, Prince George, Duke of Edinburgh, even Kate’s herself..... Nothing wrong with this, no hidden message, they just don’t include everyone in a birthday pic x,” one person wrote.

Another similarly said, “What is wrong with everyone upset they didn’t include Meghan in the picture. 1) it’s Harry’s birthday. 2.) they posted a picture of Meghan alone on her birthday and no one asked where’s Harry….! People are always looking for something where there’s nothing. That’s his brother, 3.) and all things considered… i.e. the book… why are you surprised though?”
