Queen Elizabeth II and Camilla Parker Bowles are both prepping for a grand birthday bash for Prince Charles.

The two most important women in the Prince of Wales' life want him to enjoy his 70th birthday, so they are reportedly hosting two different parties. Martin Coulter, a journalist for Daily Star, claimed that the monarch is planning to rival and upstage Camilla's party plans.

Queen Elizabeth II will reportedly make a speech in honor of her eldest son at the huge gathering she will be hosting. It will be attended by the British gentry and European royalty.

Her Majesty will host Prince Charles birthday celebration two weeks later than the Duchess of Cornwall's. Prince Harry and Meghan Markle will reportedly not attend the event that Camilla will be hosting for Prince Charles due to an official engagement abroad.

"It's going to be a very special night and Charles is very much looking forward to it," an insider told Vanity Fair about Camilla's upcoming event. "Harry and Meghan can’t be there because they will be overseas. It’s why they were so keen to be at the garden party for Charles back in May."

Although the Duke and Duchess of Sussex won't be present at Camilla's party for the future king, they would be back in London on Prince Charles' actual birthday. Also, Prince William and Kate Middleton are expected to attend the gathering that the Duchess of Cornwall will be hosting.

According to Katie Nicholl, a royal correspondent, Camilla's event would be a night of "music, opera, ballet and Shakespearean drama." It will be produced by David Whelton OBE and directed by Greg Doran, artistic director of the Royal Shakespeare Company.

In related news, on Sunday, Prince Charles, Camilla and Prince William were spotted in Balmoral. The trio accompanied the monarch in a church service at Crathie Kirk in Scotland. The Duchess of Cambridge was noticeably missing on the said outing.

It is believed that Middleton is at home with her three children 5-year-old Prince George, 3-year-old Princess Charlotte and 4-month-old Prince Louis. The royal mom of three is still on maternity leave, but she's expected to return to her royal duties next month.
