Grace Kelly's grandson dresses up as a Prince in adorable family photos

Louis Ducruet and Marie Ducruet are living their happily ever after! In February, the couple attended a birthday party in costumes with their two daughters, Victoire and Constance. Grace Kelly's 32-year-old grandson was dressed for the occasion as a Prince and his wife as a witch. The couple's older daughter Victoire looked adorable in a Snow White costume, while their youngest, Constance, was seemingly dressed like Grumpy from Snow White and the Seven Dwarfs.

"A Princess and her Prince, the Witch and "a" dwarf 😜❤️💛💙," Marie captioned the family pictures (translated to English). 

In the comments section, one Instagram user remarked that they had forgotten about their dog, Pancake, to which Marie replied (translated to English) "don't worry" and that they did not want "to impose him a Kids birthday party... he doesn't like when it's too crowded and loud..."

While Louis was dressed as a Prince, he does not have a title. However, he is the son of Princess Stephanie of Monaco.

Prince Albert of Monaco's nephew married his wife Marie in 2019. The pair welcomed their first child, Victoire in April 2023. Speaking to Point de Vue in an interview published by HOLA! USA's sister brand HELLO! in January 2024, Louis spoke about his mother's reaction to her first grandchild. "It was incredibly emotional," he recalled. "She came to the maternity ward the day after Victoire's birth, alongside my dad [Daniel Ducruet] and my paternal grandmother, as well as Marie's mum. It was a magical moment that I'll never forget."

Princess Stephanie's second grandchild, Constance, was born in December 2024. Marie announced her younger daughter's arrival on Instagram with a photo of Constance's feet as well as pictures of Victoire holding her baby sister's hand and reaching for the newborn's bassinet. "Our family is growing again with the arrival of our little Constance ♥️ Someone was eager to meet her 🥰," the mom of two wrote alongside the photos (translated to English).

Marie announced last June that she and Louis were expecting their second child. In their interview with Point de Vue earlier that year, Princess Stephanie's son and daughter-in-law were asked if they planned on expanding their family. Marie answered: “We’re not opposed to the idea. Victoire is such an adorable child, she’s making us want another. Two children would be perfect for me.”

Louis added: “We’d like our children not to have a big age gap. We’ll see what the future holds!”
