Prince Louis turns 4 on Saturday — and his parents, Prince William and Catherine, Duchess of Cambridge,

are celebrating by sharing four new pics of the birthday boy.

The adorable photos were taken earlier this month in Norfolk, England, by the former Kate Middleton, 40,

and show Louis wearing turquoise shorts and a grey sweater with stars on it as he poses on a beach.

In two of the cute pics, the toddler holds a striped red ball. In another, the prince's bare feet can be seen.

The royal couple, who have shared special birthday pics of Louis on his birthday in the past,

are also parents to Prince George, 8, and Princess Charlotte, who turns 7 on May 2.

In July 2020, the Duchess of Cambridge opened up, just a little, about Louis' affectionate nature.

During an interview with the U.K. morning show “BBC Breakfast,” the duchess mentioned how difficult it was

for her youngest child to be in lockdown during the coronavirus pandemic.
