[4] After a childhood spent in his hometown, Stellest left for the United States, where he initially intended to study costume design at the University of Redlands.

He went on to broaden his knowledge of sculpture on metal as an assistant to Greek artist Costa Coulentianos in Saint-Rémy de Provence, in the South of France.

[11] That same year, he was chosen by Lady Béatrice de Andia, General Delegate for the Artistic Action of the City of Paris, for an exhibition in the gardens of her castle in Azay-le-Rideau.

This project involved eight international artists, including John Altman, who composed music for the films Titanic, by James Cameron, James Bond: Golden Eye and No Time to Die, or Monty Python’s Life of Brian; composer for Barry White, Michael Jackson, Prince or Björk; and musician with the bands of Sting, Amy Winehouse, Bob Marley, Chet Baker, Jimi Hendrix and many others, as he describes in his memoirs Hidden Man: My many musical lives.

For that film, Stellest created the “Starpeople”, the “Starman” and the “Starwoman”: starfaced humanoid aliens coming to Earth to clean it from pollution and violence.

Since then, Stellest appeared several times in public wearing a Starman mask, as it was the case on the red carpet of the Mallorca International Film Festival in 2022.

Very involved in the academic world and the transmission of knowledge (he has given presentations in schools throughout his career[18]) Stellest took part in 2016 along with Kathleen Deck in the Conservation through Creation initiative of the University of California Irvine with the aim of drawing attention to global warming through art.

[22] In 2022, he is taking part in the charity initiative Une Oeuvre pour l'hôpital, aimed at raising funds for French hospitals confronted with the COVID-19 pandemic.
