Prince William and Prince Harry may have reunited this past week at the unveiling of a statue of their late mother Princess Diana at Kensington Palace, but a reconciliation between the brothers does not seem to be on the horizon.

Royal expert Katie Nicholl told Entertainment Tonight that William is still “very bitter” and “very hurt” over Harry’s tell-all interview with Oprah Winfrey back in March. She added that the brothers clearly tried hard to look comfortable being around one another at the event last Thursday.

“They clearly put a lot of effort to deflect from this rift between the two of them and to project on their mother’s legacy and crucially, putting on a united front to remember Diana, their mother, on what would have been her 60th birthday,” she explained.

However, she added that William has not forgiven Harry for the things he’s been saying in interviews.

“I think the end game is that it will heal, but it is going to take some time,” she continued. “The Duke of Cambridge is still very bitter and very hurt by a lot of what Harry and Meghan said in that interview particularly those allegations of racism that were labeled against the royal family.”

Despite all that has happened, Nicholl believes that the brothers will reconcile someday because of their awareness over how their damaged relationship will negatively impact the monarchy.

“So clearly, it’s going to take far more than the funeral of their grandfather and the unveiling of the statue, I think for their relationship to be anywhere near which it once was and it’s ambitious to expect that the level will be,” she said. “But I think they both recognized that a fracture that divides the important members of the royal family is something that can be ultimately damaging to the monarchy.”

While speaking to the attendees at the small event on Thursday, the brothers said, “Today, on what would have been our mother’s 60th birthday, we remember her love, strength and character — qualities that made her a force for good around the world, changing countless lives for the better.”

“Every day we wish she were still with us, and our hope is that this statue will be seen forever as a symbol of her life and her legacy,” William and Harry added.
