The Monaco royal family made quite an appearance during their annual National Day celebration [1] on Saturday. While Princess Charlene and her husband, Prince Albert II, attended a number of festivities during the day, it was their 1-year-old twins, Prince Jacques and Princess Gabriella [2], who really stole the show. The little ones looked too cute for words as they donned matching white outfits during their brief appearance on the balcony of the Monaco Palace. The last time we caught a glimpse of the royal children was when Charlene brought her son to a rugby match [3] back in February. Here's hoping there will be even more sweet outings next month as they celebrate their second birthday on Dec. 10.
