Prince Charles has reportedly heard Prince Harry's criticism loud and clear.

Recent weeks have seen Harry make unflattering remarks about his father's parenting and "pain and suffering" in the Royal Family. The comments have reached Prince Charles who is "boiling over with anger" and "really wants to defend himself," according to an Us Weekly report.

How Prince Charles feels about Harry's new interviews

Charles, 72, feels "tortured" by his son's recent interviews and the "constant digs" at him, an insider told Us Weekly. "He wishes he'd just let it drop."

The source added, "The general consensus within the royal family is to ignore Harry’s behavior, to avoid fanning the flames, but Charles is finding it hard to hold back."

The reaction comes after another report revealed Queen Elizabeth II has been left "shaken" by Prince Harry's words against the Royal Family.

Prince Harry's interview comments about parenting

Now, it seems unlikely that Prince Charles, the heir to the throne, will enter a public war of words with his son, despite his reported desire to defend himself. He was even asked about Harry's "pain and suffering" comments after he said them, but he ignored the question.

That remark was the major headline of Prince Harry's podcast interview on May 13, when he described how trauma was passed down through generations in his family via parenting.

Prince Harry has discussed Prince Charles in multiple interviews.

Then, in his new docuseries with Oprah Winfrey, the Duke further criticized the royals by saying he and Meghan were "met with total silence, total neglect" when they asked for help amid mental health struggles.

He added that Prince Charles refused to parent in a different way than he was raised, having told him as a child: "Well it was like that for me so it's going to be like that for you."

We'll see if the "constant digs" continue on Friday, as Harry and Oprah will reunite for a follow-up interview, after The Me You Can't See premiered last week.
