Kate Middleton's Happy Birthday Wishes from King Charles and Queen Camilla Include a Candid Coronation Pic

The Princess of Wales turns 42 on Tuesday.

Birthday wishes are in order for Kate Middleton -- and her royal in-laws are happy to oblige! King Charles III and Queen Camilla celebrated the day on social media by sharing a sweet candid photo from last year's coronation

"Wishing The Princess of Wales a very happy birthday today!" reads a post on X from the official Royal Family account. Kate wears a big smile on her face in the snapshot as she stands near the freshly-crowned monarch. 

The royal and mom of three turns 42 on Tuesday, Jan. 9. 

For the historic coronation on Saturday, May 6, Kate wore a blue cape and silver floral headpiece as she entered Westminster Abbey alongside her husband, heir apparent Prince William, and behind the king. 

The Princess of Wales sported an Alexander McQueen design for the special occasion: an ivory silk crepe dress with silver bullion and embroidery featuring rose, thistle, daffodil, and shamrock motifs signifying the four nations. She honored her late mother-in-law, Princess Diana, by wearing the South Sea Pearl Earrings that previously belonged to the former Princess of Wales. She also paid homage to the late Queen Elizabeth II by donning the George VI Festoon Necklace, a three-strand diamond necklace made in 1950 at the request of King George VI for his daughter, then-Princess Elizabeth. 

As for her floral headpiece, it is a collaboration between milliner Jess Collett and Alexander McQueen featuring silver bullion, crystal, and silver threadwork leaf embroidery.
