Charlotte opted for a rocker-like look sporting a sheer blouse, leather shorts, knee-high boots and a sleek coat, while her sibling, 18, wore a printed top, leather biker jacket, pants and heels. The Monaco royal led the way as she and her younger sister arrived to the show underneath the Eiffel Tower.

Charlotte often frequents the front row of fashion shows. Last week, after attending the Gucci show in Milan, the Monaco royal traveled to the City of Love with her boyfriend Dimitri Rassam to attend the Paris Opera Ballet’s opening season gala.

Back in 2015, Princess Grace Kelly's granddaughter opened up to the French magazine Philosophie about love saying, "I believe that the key to a long and happy relationship is when you both share a passion for the truth, for life.”
