Prince Harry, Meghan Markle 'Trying Their Utmost' To 'Keep The Peace' With Royal Family: Report

Prince Harry and Meghan Markle are trying their best to "keep the peace" with the royal family after their daughter Lilibet Diana's birth, a report says.

Following a series of explosive revelations over the past several months, the Duke and Duchess of Sussex are reportedly extending an olive branch to his family back in the U.K. An unnamed source told Us Weekly that Prince Harry and Markle hope to maintain a good relationship with Queen Elizabeth II and keep things civil with the other members of the firm.

"It’s no secret that the last year Harry and Meghan have been at war with the royals," the insider said. "All is not forgiven, but after all the backlash regarding their interviews — which by the way, the pair have no regrets about — they’re trying their utmost to maintain a good relationship with the queen in order to keep the peace."

The birth of Prince Harry and Markle's daughter appears to be helping ease the tensions between the Sussexes and the royal family. The Queen was the first person they called regarding Lili's arrival and was also the first to know about their intention to bestow the monarch's childhood nickname on their baby girl.

"The Duke spoke with his family in advance of the announcement, in fact his grandmother was the first family member he called. During that conversation, he shared their hope of naming their daughter Lilibet in her honor. Had she not been supportive, they would not have used the name," a spokesperson for Prince Harry and Markle said in a statement after a BBC report had claimed the Queen was not consulted before baby Lili's name was publicly announced.

The couple welcomed their daughter on June 4. However, they waited until after the second day to announce her birth through their Archewell website.

"On June 4th, we were blessed with the arrival of our daughter, Lil," the Sussexes wrote. "She is more than we could have ever imagined, and we remain grateful for the love and prayers we’ve felt from across the globe. Thank you for your continued kindness and support during this very special time for our family."

The royal family made a coordinated public effort to congratulate Prince Harry and Markle and to welcome baby Lili. However, an unnamed source told Entertainment Tonight that there were still lingering feelings of disappointment and anger toward the couple over their claims during their interview with Oprah Winfrey in March.

But royal biographer Katie Nicholl, author of "Harry: Life, Loss and Love," said she is hopeful that Lilibet will be able to help unite the royal family and the Sussexes.

"Well I think, everyone thought that this little baby is going to be a rift healer because this family division has really going on for a very long time now," Nicholl told ET. "I think, it's everyone's hope that this baby will be a peace offering in many ways and that she will help to bring this divided family back together."
