The Monegasque royal was a berry delight in a festive-red ensemble, wrapping up warm in a magnificent wool coat, matching red dress, scarlet gloves and cherry-hued heeled boots to attend a ceremony marking the National Day in Monaco.
The South African-born royal finished off her statement ensemble with a beret-style hat, sweeping her golden blonde pixie crop into a sleek side-parting.
The National Day of Monaco, also known as The Sovereign Prince's Day, is an opportunity to celebrate the history and culture of the nation.
Every year, the Princely family and the extended Grimaldi line, reflect on the traditions of their small but important nation with a series of parades and events.
Thousands of spectators watched the Prince and Princess of Monaco take to the balcony of the Palais Princier with their eight-year-old twins, waving to the crowds below.
In another poignant moment, Prince Albert and his son Prince Jacques stood to attention during a ceremony marking the National Day, as Princess Charlene and her daughter Princess Gabriella proudly held hands and looked on.
The royal family's outing marks the first time all four of them have been seen in public since Princess Charlene mysteriously deleted her Instagram account.
The former Olympic swimmer explained that the reason behind her social media cull was simple - her children are getting older, and she wants to protect their privacy. In a candid interview, the 45-year-old said she wants to keep the twins away from the "pressure" of public life.
She also commented that she's "grateful" the pair will always have each other. The Monaco royal kids are also experiencing a "big change" at school this year, as it marks the first time they have been placed in separate classes.

"It’s the first time Jacques and Gabriella won’t be in the same class. It’s a big step for them, and it feels right," Charlene told publication Monaco Matin.
"Like any other pupil going back to school, they had a lot of questions: about their new classmates, their teachers, what they were going to wear on their first day. They did still ask me when their next holiday would be, though!"
