Prince George and Princess Charlotte’s next royal outing has just been teased.

Kat Hopps, a journalist for Express, said that the royal siblings will make an appearance at the wedding of Lady Gabriella Windsor and Thomas Kingston on May 18.

After the royal wedding, Prince George and Princess Charlotte will once again be seen in public at this year’s Trooping the Colour on June 8. But ahead of these two events, Princess Charlotte will first celebrate her 4th birthday on May 2.

To commemorate the young princess’ special day, Prince William and Middleton will most likely release a thank you card addressed to those who will send their daughter their well-wishes.

Prince George, on the other hand, will turn 6 years old on July 22. And his youngest sibling, Prince Louis, will turn 1 year old on April 23.

In related news, Prince George and Princess Charlotte made headlines today after they were spotted on a day out while their parents were out on royal duties. Twitter user Netty Royal spotted the siblings with their nanny Maria Borrallo playing on the grounds of Kensington Gardens on Sunday.

“When you walk around Kensington Gardens before departure and you see the nanny with all three kids,” she tweeted.

The Twitter user also claimed to have seen Prince Louis being pushed by Borrallo in a pushchair. Prince George and Princess Charlotte also raced each other in their bicycles.

Prince William and Middleton were at the Hounslow in west London on Sunday to visit the 1st Battalion Irish Guards at their base. The Duke and Duchess of Cambridge watched 350 soldiers take part in the parade before Prince William led a salute.

After the parade, Middleton handed out shamrocks to officers in a tradition which started in 1901. Middleton and Prince William reunited with their three children at home after the event. There are rumors that another addition to their growing family may be announced this year.
