  • The Duke and Duchess of Cambridge are unlikely to invite Prince Harry, Meghan Markle and Prince Andrew, according to Russell Myers

Queen Elizabeth plans to host a birthday bash for Prince William and Kate Middleton to celebrate their milestone birthdays this year, according to a journalist.

The Duke of Cambridge turned 40 Tuesday, while his wife celebrated her 40th birthday on Jan. 9.

Russell Myers, royal editor at Daily Mirror and co-host of the "Pod Save The Queen" podcast, claimed on "Today Extra" that the Queen, 96, "has agreed to throw [Prince William] a big party" to celebrate his major milestone. International Business Times could not independently verify this information.

"It's part of a royal tradition that she likes to throw a big party for the royals' 40th birthdays," Myers added. "And of course, Kate missed her birthday in January because of the surge in COVID rates here in the U.K., so Prince William and Kate are going to have a joint birthday party. Apparently, this is going to be at the Queen's Windsor Castle home later this summer."

The future king and queen consort are expected to invite their family members and friends to the bash, but some royals are unlikely to be included in their guest list, the royal expert claimed.

"Prince Harry [and] Meghan [Markle] probably won't be on the list. Prince Andrew probably won't be invited. But I'm told it'll be a big party extravaganza to welcome the big 40," Myers continued.

When asked where Prince Harry and Prince William currently stand, Myers claimed that the brothers' relationship is "strained in the extreme at the moment" and that it would take a lot more work and time before they can fully reconcile.

Myers pointed out that there was no interaction between Prince Charles' two sons when they attended the National Service of Thanksgiving in honor of the Queen at St. Paul's Cathedral on June 3.

"They didn't spend any time together over those four days of the Platinum Jubilee," claimed the journalist, who said he was present during the service.

Meanwhile, Prince William spent his birthday privately with his family Tuesday, the BBC reported, citing Kensington Palace.

The palace released three never-before-seen photos of the duke to mark the occasion. The images, which were taken two weeks ago, showed Prince William selling copies of the Big Issue, a magazine which is sold by the homeless and long-termed unemployed, on the streets of London, according to the outlet.

Prince William, Middleton and their three children, Prince George, Princess Charlotte and Prince Louis, are set to move from their London home base at Kensington Palace to Windsor, where the Queen resides, this summer, the BBC reported.
