Kate Middleton is standing by her man.

Royal sources have insisted the Duchess of Cambridge has been a shoulder to lean on for her husband Prince William as he copes with his rift with Prince Harry.

"Kate is a natural leader who has a magnificent ability to remain composed, even during the most challenging situations," a palace insider told Us Weekly for their new issue.

"Kate’s used to all eyes being on her," another source claimed to the outlet. "Being in a strong, solid marriage to William helps. They lean on each other for support during difficult times and will talk through their problems. She’s been her husband’s pillar of strength throughout this whole ordeal."

PRINCE HARRY, PRINCE WILLIAM MAY NEVER 'HAVE THE SAME CLOSENESS,' ROYAL EXPERT CLAIMS: 'IT’S GONE TOO FAR'

On March 7, CBS aired a two-hour interview that the Duke and Duchess of Sussex did with Oprah Winfrey. During the televised sit-down, Harry, 36, revealed that his relationships with his father Prince Charles, 72, and older brother William, 38, have ruptured.

Meghan Markle, 39, described feeling so isolated and miserable inside the royal family that she had suicidal thoughts. The Duchess of Sussex also alleged that a member of the royal family had "concerns" about the color of her unborn child’s skin.

The family member was not Queen Elizabeth II, 94, or Prince Philip, 99, according to Harry, sparking a flurry of speculation about who it could be.

Harry also told the media mogul, 67, the royal family cut him off financially at the start of 2020 after announcing plans to step back from his roles. But he was able to afford security for his family because of the money his late mother Princess Diana left behind.

After the interview aired, Charles was questioned by a reporter about the interview during a visit to a vaccine clinic in London but remained silent. When William was approached during a visit to an East London School, he declared, "We’re very much not a racist family."

During the interview with Winfrey, Harry said he will "always be there" for his brother despite their differences.

"I love William to bits," Harry said. "He's my brother. We've been through hell together. But we are on different paths."

When asked by Winfrey how he would describe the relationship now, Harry said, "space," adding, "Time heals all things, hopefully."

A source told the outlet that William and Middleton, 39, were "in total shock" after hearing Markle and Harry’s allegations. One insider alleged that William, who is second in line to the throne, was "fuming" because he "absolutely does not support speaking out against the crown."

Gayle King later revealed on "CBS This Morning" that Harry spoke to his brother and father. However, those conversations "were not productive."

The brothers are scheduled to reunite on July 1 at Kensington Palace for the unveiling of a statue they commissioned in honor of their mother.

"For all their differences, the two are still totally bonded on preserving their mother’s legacy," a source told the outlet. "It’s a real shame that they’re on such bad terms going into this because it’s going to be very emotional."

After Harry and Markle married in May 2018 at Windsor Castle, the royal family seemed to welcome the Duchess of Sussex, a glamorous former TV star. The pair were seen as providing a fresh young face for the monarchy of an increasingly multicultural nation.

It didn’t take long for the fairy tale to unravel. 

The couple stepped away from royal duties last year and eventually settled in California, saying they wanted to escape racist coverage and unwanted intrusions on their privacy by the British media.
