It was arguably the biggest event since her wedding in July of this year. But Princess Charlene of Monaco was the epitome of cool as she celebrated her nation's first National Day in an official capacity.
The blonde South African has accompanied Prince Albert to the celebrations in previous years, but this was her first appearance as a princess.
And, despite having to recently deny runaway bride reports on a US chat show, Albert and Charlene looked blissfully happy as they led the festivities.
The morning ceremonies saw the pair take to the balcony in Monaco Palace Square.
Elegant in beige, Charlene smiled and waved to the crowds in the square below as Albert stood proudly by her side.
The royals looked close as they exchanged intimate smiles and entwined hands in a show of unity.
It was a family affair as Albert's sisters - Princess Stephanie and Caroline – strolled alongside their new sister-in-law during the parade.
Caroline's daughters, Charlotte Casiraghi and Alexandra were also in attendance.
The patriotic party culminated in a concert at the Grimaldi forum where Charlene opted for muted glamour in a brown, floor length gown and sleek up-do.
Then the princess was presented a bouquet of flowers by children dressed as Pierrots.
