Prince William, Kate Middleton’s cold birthday message to Prince Harry has caused quite a bit of stir amid fans and experts.

Experts recently sat down to weigh in on Prince William and Kate Middleton’s decision to send Prince Harry a rather ‘cold and frosty’ birthday message amid ongoing tensions.

The observation was discussed at length by royal expert Natalie Oliveri and during her interview with the Today Show, she was quoted saying, “Well, if Harry was looking for a warmer happy birthday message from his family, he hasn't really got that.”

“We did see a couple of messages from the Royal Family's Twitter account, but it's one message from Prince William and Kate's Instagram story that has a lot of people suggesting that their happy birthday message to Harry was rather curt.”

“Now, in the past, Kate and William have actually posted a photo of Prince Harry on his birthday to their Instagram, including one last year of the three of them looking very happy during a charity race, and then the year before it's a photo from the royal wedding.”

“Look, it's just Happy Birthday Prince Harry, it is quite cold in comparison to what they have done in the past.”

Before concluding she added, “I guess it's just another sign that that tension between Harry and his family is still there, although we did see a slightly warmer message from Queen Elizabeth's account and also Clarence House, Harry's father.”
