Prince George and Princess Charlotte’s next public outing may be at Charlie van Straubenzee’s wedding on Aug. 4.

Lauren O’Callaghan, a journalist for Express, said that it is possible for Kate Middleton and Prince William to bring their two older children along to van Straubenzee’s wedding to Daisy Jenks.

It is important to note that Thomas van Straubenzee, the younger brother of Jenks’ future husband, is Princess Charlotte’s godparent. O’Callaghan said that due to this, Prince George and Princess Charlotte may not only attend the wedding; they might also be part of the entourage.

Two members of the royal family that are guaranteed to attend the nuptials are Prince Harry and Meghan Markle. Tim Rooke, a royal photographer, previously confirmed that Prince Harry will be van Straubenzee’s best man.

“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. Can’t do everything!” he previously tweeted.

Prince Harry and van Straubenzee consider each other best friends. The latter was also present during the former and Markle’s wedding on May 19. The royal couple tied the knot at St. George’s Chapel in Windsor Castle.

Van Straubenzee’s Aug. 4 wedding will also fall on the same day as Markle’s 37th birthday. Francesca Specter, a journalist for Express, said that it is possible for the Duchess of Sussex to take a break from her strict diet to celebrate her special day.

On her Lifestyle blog, The Tig, Markle said that she loves eating fries and chips. However, since becoming vegan, she has adhered to a healthier lifestyle.

“Meghan, who is also a foodie, has her vices just like the rest of us – and will no doubt enjoy these on her birthday,” Specter wrote.

On her now-deleted blog, Markle previously wrote, “French fries and vino are my vices. I’m always hoping I’m having lunch with people, so we can share fries. It’s its own food group for me.”
