The comparisons didn’t stop there, either.

One commenter suggested Gabriella resembled her late grandmother Grace Kelly, while another insisted Jacques was the spitting image of his aunty, Princess Stephanie.

Gabriella Thérèse Marie and Jacques Honoré Rainier were born on December 10 2014, meaning they have celebrated their third birthday just this week.
