Meghan Markle and Prince Harry are once again being called out for how they honoured one of their fellow royals' birthdays on social media.

Just over a month after the Duke and Duchess of Sussex were slammed for their "cold" birthday message to Prince William, the couple is in hot water with royal watchers for how they commemorated his son, Prince George's, sixth birthday on Monday.

After Kensington Palace shared exclusive new photos taken by George's mum, Kate Middleton, in honour of his big day, Harry and Meghan commented on one of the posts via the Sussex Royal Instagram account, writing, "Happy Birthday! Wishing you a very special day and lots of love!"

Naturally, people criticised them for not sharing an actual post for George's birthday.

"You're not earning any respect with your comments," one person wrote, calling back to their comment for William's birthday.

"Why so disrespectful?" another user replied, while another had a request for the couple: "Please include 'HRH Prince George' next time as sign of RESPECT to the future King."

"One day Prince George will teach you how to be respectful, you will remember this Day," another critic responded.

There were other users who came to Harry and Meghan's defence, saying that "this is how we [wish someone happy birthday] in normal life people."

"Your greeting as always is sweet and heartfelt. Keep ignoring the haters. They don't care about your nephew or they wouldn't have used his birthday to justify attacking another human being with such vile comments," another one of Harry and Meghan's fans said. "If Kensington Royal or the Queen had an issue with your greetings they would have asked you to change it, but haven't. You are family. Period."
