On Saturday, the royal family attended the christening for baby Archie. However, two important family members were noticeably missing, Queen Elizabeth II and Prince Phillip. Their absence left fans of the royal family confused. However, royal commentator Rob Jobson divulged to "Sunrise News" that he believes it was due to a "simple calendar error."

"We were told that the Queen couldn't make it because of a prior engagement," the host of "Sunrise News" said as reported by Express, adding, "But it seems it was a diary blunder by Harry and Meghan, is that right?"

"Yeah, they didn't do the checking by the sounds of it," replied Jobson.

By the time they had realized their mistake, Jobson said the queen "had already arranged to have a weekend with the Duke of Edinburgh in Sandringham."

Continuing, he added, "So, they just didn't get the diary dates right. I mean, it is not the first time that the Queen, who is the great grandmother, after all, has missed a christening. I mean, as long as the grandparents were there, well, [Prince] Charles and Doria [Ragland] were there, I suppose that's okay."
