Charlotte Casiraghi mingles with Hollywood while in NYC with boyfriend Dimitri Rassam

Hollywood and royalty collided in the Big Apple on Monday evening. Princess Grace Kelly's granddaughter, Charlotte Casiraghi, stepped out on April 3 for the Montblanc & UNICEF Gala Dinner, where she mingled with actor Hugh Jackman. The Monaco royal was a vision in white wearing a long sleeve v-neck dress by Giambattista Valli, while sweeping her brunette tresses into an elegant updo for the occasion. Diane Kruger, Olivia Palermo and Victoria’s Secret Angel Elsa Hosk were also in attendance for the star-studded event that celebrated the partnership between the organization and luxury company, which aims to improve learning conditions for children around the world.

Charlotte, 30, traveled to New York a few days prior to the gala dinner with her new boyfriend Dimitri Rassam, who is the eldest son of French actress Carole Bouquet. The mom-of-one was photographed arriving to John F. Kennedy International Airport on Saturday with her three-year-old son Raphaël Elmaleh and film producer beau.

The couple’s trip comes a month after the two spent time together in Paris and at Charlotte's new country residence in Barbizon. Back in 2015, Princess Caroline's daughter 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.”

Before Dimitri, Charlotte was linked to Italian director Lamberto Sanfelice, whom she dated after splitting from the father of her son, Gad Elmaleh. The French comedian confirmed last May that he and the Monaco royal had split, though he noted: “We stay close. We are a family.”
