Regardless of its size, planning a wedding is certainly a daunting task.
Before most couples tie the knot, there are several responsibilities the bride and groom have to take care of before they walk down the aisle, such as making the guest list, choosing a venue, and picking out the menu and decorations.
And as you can imagine, this stress is only multiplied by a tenfold when you're a member of the royal family.
"What Meghan wants, she gets."
While fans of the royal couple were in awe of Prince Harry and Meghan Markle's wedding this past spring, very few people knew how stressed they were behind the scenes.
But an upcoming tell-all by royal correspondent Robert Jobson titled, Charles at 70: Thoughts, Hopes and Dreams, Harry's temper skyrocketed leading up to the big day.
"The weeks leading up to the wedding had been far more tense for both Harry and Meghan than most people realized," an excerpt of the book to Daily Mail said, adding that the Prince was known to have "raised his voice on occasion."
"In fact, [Harry and Meghan] both felt so stressed that they’d booked a series of appointments with Ross Barr, known as 'the acupuncturist to the stars.'"
Jobson also alleges a "petulant" and "short-tempered" Harry screamed, "What Meghan wants, she gets" in one of his rants to the royal staff before the nuptials took place.
While it may come as a shock to some that Harry could become so irritable, Jobson claims he and Prince William have been prone to "extreme mood swings" throughout their lives.
"She could be your best friend one minute and the next, your worst enemy."
In the biography, Jobson asserts the two Princes took after Princess Diana and her supposed volatile personality.
He added that their unpredictable temperament greatly concerned Prince Charles, who was frequently left stunned over the "level of belligerence" his children showed him.
"William has even been known to speak firmly in his father's face...reminiscent of his mother's hot temper which Charles had to deal with on a regular basis during their marriage," Jobson wrote.
"To this day, Charles admits he often finds it difficult to gauge either of his sons' occasionally unpredictable moods."
A source close to the royal family told the biographer said like his late mother, the Duke of Sussex also "wears his heart on his sleeve," and is also more prone to "emotional outbursts."
A former courtier is said to have echoed those sentiments, and said, "They both have quite extreme mood swings, just as Diana did. She could be your best friend one minute and the next, your worst enemy."
But despite the royals' outbursts, it appears that the addition of Meghan into the family has helped calm the waters, especially when it comes to her husband and father-in-law's relationship.
"She told Prince Harry he was wonderful, welcoming, warm, hard-working, kind and stable. She made it clear that he should appreciate him and bond more."
