Meghan Markle and her son, Archie starred in one of the newest Save With Stories videos shared online by Save the Children UK.

The over two-minute clip was released to commemorate Archie’s first birthday on Wednesday, May 6. In the video, Markle reads “Duck! Rabbit!” to her adorable son, who is sitting on her lap.

Thousands of royal fans commented on the video by gushing on Archie. Some of them also donated to the foundation after seeing the sweet moment between the Duchess of Sussex and her little boy.

But other eagle-eyed royal fans also noticed a mysterious sticker on the front page of the children’s book. The pale blue sticker has the words “Archie’s Book Club” on it.

On Twitter, one royal fan said that the sticker must have been a gift from Oprah Winfrey. The popular talk show host is good friends with the Duke and Duchess of Sussex.

“They book they’re reading could be a gift from Oprah. It has an ‘Archie’s Book Club’ sticker on the front and Oprah likes to give personalized ‘book clubs’ as a baby gift,” the royal fan said.

According to Express, Winfrey ran a book club discussion segment on the “Oprah Winfrey Show” over the course of 15 years. Throughout that time, the talk show host recommended 70 books that she thinks are worthy of attention.

Meanwhile, the Sussexes celebrated Archie’s first birthday at the comfort of their home in Los Angeles. Due to the coronavirus pandemic, Prince Harry, Markle, and Archie were unable to celebrate with their loved ones.

But on social media, the members of the royal family paid tribute to the adorable 1-year-old. Prince William and Kate Middleton shared a photo from Archie’s christening last year. Prince Charles and Camilla also uploaded a photo from Archie’s christening where Queen Elizabeth is doting on him.

A source told Closer Weekly earlier this week that the Sussexes also organized FaceTime calls with the royal family and Markle’s mom, Doria Ragland.

The insider claimed that Prince Harry and Markle are already thinking about expanding their family since Archie is growing up.

“Now that they’ve begun to settle into their new life, the couple have started thinking about having another child. Another baby is almost definitely in the cards — sooner rather than later. It wouldn’t be surprising if Meghan becomes pregnant before the end of the year,” the source said.
