The Duchess of Sussex, formerly Meghan Markle, will be turning 37 on Saturday August 4, but the new royal won't be celebrating the occasion with a lavish party, neither will she be jetting to Africa as she reportedly did on her last birthday with Prince Harry, 33. Instead, the Duchess will be enjoying someone's else's big day.
Prince Harry and Van Straubenzee were peers at Ludgrove Prep School and have been friends ever since.
"Unfortunately I will be missing the wedding of Charlie Van Straubenzee and Daisy Jenks where Prince Harry will be best man on August 4th in Churt Surrey as I will be on the beach," Rooke tweeted. "Can't do everything!"
Although attending a wedding on her birthday, Meghan will be surrounded by her family as it's expected the Duke and Duchess of Cambridge will also be guests of the Van Straubenzee wedding.
We have everything crossed for an appearance from the youngest royals, Prince George, Princess Charlotte and tiny Prince Louis, however it is not known if William and Kate's children will attend.
The groom's older brother Thomas Van Straubenzee is one of Charlotte's five godparents.
In a sweet coincidence, Meghan's birthday falls on another important date to the royal family. The Duchess shares the same birthday as the Queen's mother, Elizabeth Bowes-Lyon. The Queen Mother passed away in 2002. The Duchess and the Queen already have a charming bond, perhaps this connection has brought them even closer.
