Sienna Rose

The act drew wide attention in January 2026, when it was nearing three million monthly Spotify listeners and had three songs, Into the Blue, Safe With You and Where Your Warmth Begins, on Spotify's Viral 50. Deezer told the BBC, Rolling Stone and TechRadar that many of the act's albums and songs are detected and tagged on its platform as AI-generated, and TechRadar reported this as confirmation that Sienna Rose is an AI artist.

Reporters pointed to the absence of gigs, videos and any real social media presence, and to the pace of releases: at least 45 tracks between 28 September and 5 December 2025. Selena Gomez used Where Your Warmth Begins on an Instagram post about the Golden Globes, and the song was later removed from the post. The BBC noted that several of the songs appeared to be credited to the US label Broke, which does not list Sienna Rose among its signings.

No human performer behind the voice has been identified; RouteNote describes the project as a virtual artist identity run by an unidentified creator or team. By September 2026 the main Spotify profile had fallen to around 400,000 monthly listeners.
