Latest Update on Prince Harry and Prince William's Relationship

Prince William and Prince Harry have had a rocky relationship for years as the two formerly close brothers lead very different lives. Robert Lacey, author of the book Battle of Brothers: William, Harry and the Inside Story of a Family in Tumult, told Page Six that the current state of their relationship is "poor, definitely poor." Lacey explained that William hosted a party thanking people who were involved in the unveiling of the sculpture of their late mother, Princess Diana, at Kensington Palace in July and that his anger towards his brother is still quite apparent.

"I've spoken to two people from that party and it was quite clear from things he said that his anger towards Harry remains," Lacey dished. "He remains unhappy about what his brother has done. There is no immediate possibility of any reconciliation. I mean, it's not wanted on either side. Too many bitter things have been said."

Rumors circled in October that Prince William stopped Prince Harry and Meghan Markle from crossing the pond to hold their daughter Lilibet's christening ceremony at St. George's Chapel at Windsor. Prince Harry and Meghan Markle still haven't shown off their new child to the world yet, breaking from the royal tradition by waiting so long.

NBC royals correspondent Neil Sean tells the Express the couple was hoping to host the religious ritual among family in the hopes that they could mend some of their broken relationships. Though, it doesn't look like they'll be doing that anytime soon.  "Both Harry and Meghan were very keen to make that return and make sure that christening happened, particularly in front of Her Majesty The Queen," Sean said, according to Express. "But that came to a grinding halt."

He added: "[M]oving forward, there was one person who basically decided there wasn't an appetite for this and the person that seemingly is, so far, not willing to kiss and make up with his younger brother...According to a very good source, Prince William was the one who basically said 'no, we don't think this is going to work,' it wasn't a particularly good idea."

Despite the brothers being photographed together on various occasions, posing at their grandfather Prince Philip's funeral as well as the unveiling of their mother's statue, the two likely won't be spending any quality family time together for the time being. "It's perhaps unlikely that they're going to be spending what we would think of as quality time together at Christmas and New Years and birthdays," royal expert Jonathan Sacerdoti told Us Weekly. "Just remember that the queen hasn't met her latest grandaughter. It doesn't seem likely that she's going to anytime soon. She's barely seen Archie for quite a while," he continued. "On a human family level, forgetting them being the royal family, there's already quite some frostiness and distance there. So I suspect if things can go well, [then] maybe they'll have the occasional meeting, but I don't think it seems very high on anyone's agenda."
