Jean Arnault

It didn't take long for the youngest Arnault heir, 24-year-old Jean, to start moving up the ranks of LVMH himself.

With master's degrees in mechanical engineering from Imperial College London and financial mathematics from MIT, Jean became the marketing and development director of Louis Vuitton's watch division in August 2021 and is currently the brand's head watch director. Needless to say, he frequently compares notes with brother Frédéric.

Smart and social, the buzzy boy-about-town is known to hit the scene with his stylish strategist-slash-influencer girlfriend, Zita d'Hauteville. Quite the chic young pairing!
