He has made headlines selling pasta on the streets of Los Angeles, produced several short films and captured the hearts of millions of viewers when he entered the Italian version of "Strictly Come Dancing."
Now Prince Emanuele Filiberto of Savoy, the 52-year-old grandson of the last Italian king, has joined forces with seven other royal families in developing a new video game that will share their legacy with a new generation that has never heard of them.
The game, which is titled "The RoyaLand," is being played with deposed royal heirs from Albania, Bulgaria, France, Yugoslavia, the Russian Romanov family and the German Mecklenburg dynasty, as well as the ruling monarchs of Lesotho in Southern Africa.
"My idea was to create a game that could combine the allure of the royal family and the excitement of games, including other royal families," Prince Emanuele Filiberto told The Telegraph in an exclusive interview.
"I think it's a win-win situation for both players and the Royals," he said.
The prince has not yet approached the British royal family, but said he had discussed the proposal with Prince Albert of Monaco, where Emanuele Filiberto lives with his family.
Supported by Artificial Intelligence, the video game is being produced in collaboration with Milan-based Neosperience and is expected to be released at the end of next year.
The game's promotional material includes a prince avatar and invites players to interact with royal families in a "cooperative experience" where they battle their rivals for supremacy to strengthen their virtual kingdoms.
"It is not only a complex game where players must own their land, but increase their power, wealth and territory, and also (pass) the hierarchy of nobility to become the king or queen of "RoyaLand" and hold this title," the prince said without any irony.
Princess Victoria, an ordinary Italian citizen who married Grand Duke George of the Romanov family of Russia, who is also a cousin of Emanuele Filiberto, described the video game as "state-of-the-art."
"It's a new way of approaching history," the princess told The Telegraph by phone. "The younger generation spends a lot of their time on social media and video games can be quite shallow. But this will be educational and it will be fun," she added.
Born in Geneva, the boyish-looking Emanuele Filiberto grew up in exile and has made no secret of the challenges of defining his role since the monarchy was rejected by Italians in a nationwide referendum in 1946.
After being allowed to enter Italy after a constitutional ban was overturned, the prince became a household name with his victory on Italy's highest-rated Dancing with the Stars. He has previously spoken of his desire to enter politics, aspiring to become prime minister.
But he is adamant that "RoyaLand" has nothing to do with legitimizing the Savoy name or advancing any aspirations to restore the monarchy.
"It's not a game that's going to bring me back," he said. "It's about trying to pass on a history, a culture and values to a new generation."
