Kate Middleton is said to be returning to her royal duties in under three weeks.

International Business Times reports that Queen Elizabeth II intends for the Duchess of Cambridge to be in attendance during her birthday parade on June 13.

The Queen, whose actual birthday is on April 21, celebrates her official birthday on a Saturday in June. According to the official website of the British Monarchy, the Queen's official birthday is celebrated publicly on a day when the weather is more enjoyable to carry out the traditional "Trooping of the Colour," a military ceremony followed by an air show, which the Royal Family watches from the Buckingham Palace balcony.

Despite original reports that said the Duchess was looking forward to a longer maternity leave the second time around, the parade comes just six weeks after the birth of Princess Charlotte, making it just a few days longer than the 39-day leave she took after the birth of Prince George.

Kensington Palace announced Prince William's return to work (after a two-week paternity leave) on May 18 after he attended a United For Wildlife talk in Switzerland.

The palace has not released any further public appearances by the Duchess of Cambridge at this time.
