Queen Elizabeth II is reportedly planning a huge birthday for her eldest son Prince Charles.

Latifa Yedroudj, a journalist for Express, revealed that the Buckingham Palace has already sent out invitations to hundreds of guests who have been asked to attend the bash in the State Rooms on Nov. 14.

At the event, the Queen will pay tribute to Prince Charles, and Her Majesty’s funds will be the one to shoulder the expenses for the celebration. Prior to Prince Charles’ birthday, the royal family organized several gatherings to commemorate the future king’s special day.

In May, the royal family attended a Garden Party in May. The gathering served as the first gathering that Meghan Markle and Prince Harry attended after their royal wedding at St. George’s Chapel in Windsor Castle.

The Nov. 14 birthday bash will be attended by Prince Charles’ family members, as well as the relatives of his wife Camilla Parker Bowles. Prince Charles will also be featured in two documentaries on BBC to honor his 70th birthday parties.

In related news, Prince Charles also made headlines this week after it was revealed that his ex-wife, Princess Diana, didn’t want to file for a divorce from him.

Jenni Rivett, a celebrity trainer who worked with the Princess of Wales, said that the mom of two wanted to keep her marriage to Prince Charles even after she learned that about his affair with Bowles.

“Given the choice, she would have stayed and tried to make a happy marriage. She loved Charles. She married for the right reasons. She married for love. It wasn’t her that asked for all of this. It was sprung upon her. She wasn’t the one that wanted to separate or have a divorce,” she told Fox News.

Rivett also said that Princess Diana opened up to her about her personal struggles.

“She wanted to be the Princess of Wales and the Queen of the people’s hearts. She wanted to be a loving mother, which she was, and a loving wife,” Rivett said.
