Born in 1994, Laëtitia Kerfa, aka Original Laeti, is of Algerian and Guadeloupean origin. She got her start in rap with the Keskiya collective. Her real breakthrough came in 2019 with the show Du sale! conceived and directed by Marion Siéfert, which she helped create and perform alongside choreographer Janice Bieleu. Thanks to this experience, she was spotted by actor and producer Franck Gastambide, who asked her to join the cast of the second season of his hit series Validé, which explores the backstage world of French rap. She plays the lead role, that of Sara. Preparing her first album for 2022, Laeti took advantage of the series' media aura (over 10 million views in the first week of broadcast) to place her single "Briller " at number 45 in the French charts.
