Queen Mathilde and King Philippe of Belgium hosted a majestic state banquet on Tuesday evening – and in a royal first, they were joined by all four of their children.
The Belgian royal family rolled out the red carpet for Emperor Naruhito and Empress Masako of Japan at Laeken Castle in Brussels to begin their three-day state visit.
The couple's youngest child, 18-year-old Princess Eleonore, even made her debut in a tiara, wearing a previously unseen item from the royal collection.
