While all of the Luxembourg royals came out to meet the Pope on TK, it was one in particular who stole the show: Princess Amalia. The littlest member of the family was among the children and grandchildren of Grand Duke Henri and Grand Duchess Maria Teresa, all of whom made the trip to Vatican City a family affair.
The little girl, who is the one-year-old daughter of Prince Felix and Princess Claire, was the picture of cuteness in a white dress with a pink bow. She was as good as gold as she was introduced to Pope Francis and stood next to the 79-year-old Catholic leader during the photocall.
After the pictures were taken, Amalia didn't want to leave her grandmother's side and Maria Teresa sweetly scooped her up in her arms.
The family enjoyed a private meeting with the Argentinean religious leader, with Cuba-born Maria Teresa greeting Pope Francis in the pair's native Spanish.
The Grand Duchess was the only female royal to wear white, adhering to the "privilège du blanc " rule which states that only a Catholic queen or princess, or one married to a Catholic monarch, can wear the colour.
The rest of the group including Maria Teresa's daughters-in-law Princess Stephanie and Princess Claire all wore black.
The Pope presented the Grand Duke and the Grand Duchess with a peace medallion and an encyclical on the environment. As they left, the Pope bid the couple – who have been married for 35 years – farewell with a private joke as he laughed and said: "I also congratulate you for the conversation you have had."
Meeting the Pope was the perfect excuse for the Luxembourg royals to gather and celebrate together. Maria Teresa is turning 60 on Tuesday and she will no doubt have been thrilled to spend the lead-up of her milestone birthday surrounded by her children and grandchildren.
