Princess Charlene lights a fire in honor of Sainte Dévote in Monaco

Joined by her husband Prince Albert, Princess Charlene of Monaco stepped out on Tuesday for the annual Sainte Dévote's Day, a celebration in honor of Monaco's patron saint. The stylish mom-of-two, who celebrated her 38th birthday on Monday, took part in such familiar royal duties as a balcony appearance as well as a more unusual activity – setting a small fishing boat on fire – that is a local tradition that began during Prince Louis II's reign in 1942.

Charlene looked chic in an on-trend poncho paired with a grey scarf as she cozied up to her husband, linking her arm around his as they stood in the crowd and watched the blaze light up the evening.

On Wednesday, Charlene and Prince Albert continued to remember Monaco's patron saint. The couple gathered on the balcony of the Palace to attend the ceremony of the Sainte Dévote. The royal mom looked chic yet again in a navy coatdress and scarf.

The national holiday fell just a day after Princess Charlene's 38th birthday, which she marked privately with her husband and their 1-year-old twins Crown Prince Jacques and Princess Gabriella.

The royal couple's evening out was the first high profile event that they have attended since their private audience with the Pope earlier this month. For that occasion, elegant Charlene wore all-white according to the "privilège du blanc" rule – only a handful of designated Catholic Queens and Princesses are permitted to wear the hue for a Papal visit, and Charlene is one of them.
