Time for the Buckingham Palace Easter Egg hunt, little William.

There are few shows we are more excited for a new season's debut of than Netflix's The Crown. The first three seasons have delighted and stumped us, frightened and shocked us. Now, the fourth season of the hit show—which has racked up Golden Globe, Screen Actors Guild, and Emmy awards, to name a few—is shaping up to be one of the most fascinating yet as it documents the stories of Prince Charles, Princess Diana, and Prime Minister Margaret Thatcher, among others, from the late 1970s up until about 1990.

Now, according to Good Housekeeping, Emma Corrin, who plays Princess Diana in the series, has been spotted on the show's set with a child who is playing her son, William. "The actors can be seen filming a Buckingham Palace Easter Egg hunt in 1984, with Emma wearing a prosthetic bump to signify Diana's pregnancy with Prince Harry," writes Megan Sutton in the Good Housekeeping article.  Since Prince William was born in June of 1982, this puts him a few months shy of two-years-old in the scene. "The pictures show Emma holding the child star in her arms and chasing after him affectionately." As shared by Harper's Bazaar, this isn't tot Prince William's first cameo on the show, as he was also seen on the set while the show was filming scenes reenacting Prince Charles' and Princess Diana's royal tour of Australia, which took place in the early 1980s.

Of course, while these behind-the-scenes glimpses of The Crown reveal a taste of what the fourth season's plot will entail, they can only give away so much, and we're looking forward to see what unfolds in the next season of the series.
