Michelle Trachtenberg has died at just 39 years old. The late starlet — who is known for countless film and television roles — was found dead in a New York City apartment on February 26, 2025. Though authorities reportedly are not investigating any foul play in her death, fans were shocked about the news and wondered how the young actress died.

Following news reports that the former child actor had recently undergone a liver transplant, top U.S. health experts explain what conditions cause the largest organ in the body to fail.

Years later, Trachtenberg — who also appeared in films 17 Again, Ice Princess — voiced Judy Reilly on Human Kind Of in 2018 before reprising her role as Georgina in 2022 and 2023 episodes of the short-lived revival of Gossip Girl. She also served as an executive producer for 2021’s Meet, Marry, Murder series, which she also hosted.
