Kianna Underwood, the former child actress best known for her role on Nickelodeon’s sketch series All That, has died at the age of 33 following a hit and run incident in New York. Her family confirmed the news in a social media post, prompting an outpouring of grief from fans and former viewers who grew up watching her on screen.

According to police, officers responded to reports shortly before 7am of a pedestrian being struck by a grey vehicle at the intersection of Pitkin Avenue and Mother Gaston Boulevard in Brooklyn. Authorities said the victim suffered severe trauma to her head and body and was pronounced dead at the scene by emergency services. The driver left the scene and no arrests have been made so far, with the NYPD Highway District Collision Investigation Squad continuing to investigate the incident.

Underwood rose to prominence as part of the tenth season of All That, appearing on the long running Nickelodeon series during 2004 and 2005. The show had previously launched the careers of major stars including Amanda Bynes and Kenan Thompson, and Underwood’s time on the programme made her a familiar face to a generation of young viewers.

Beyond All That, Underwood built a varied career across television, film and theatre. She lent her voice to the animated series Little Bill, which aired between 1999 and 2004 and featured an ensemble cast including Phylicia Rashad, Gregory Hines, Tyler James Williams and Ruby Dee. She also appeared in the 1999 film The 24 Hour Woman alongside Rosie Perez and Patti LuPone, and voiced a character in the 2001 television movie Santa, Baby! with Patti LaBelle, Vanessa Williams and Eartha Kitt. In addition, Underwood was cast in the original national tour of the musical Hairspray, further showcasing her range as a performer.

News of her death has sparked widespread reaction online. Fans have shared clips, photos and memories from her Nickelodeon years, with many expressing shock at the sudden loss. Messages of condolence have flooded comment sections, while posts remembering her talent and early promise have circulated widely across social media platforms. Several viewers described how All That shaped their childhoods and credited Underwood as part of that shared experience.

As tributes continue to grow, questions remain around the circumstances of the crash and the search for the driver involved. For many, however, the focus has been on remembering Underwood’s contributions to children’s television and the mark she left on pop culture during her early career. Her death has resonated deeply with fans who remember her not only as a performer, but as part of a formative era in Nickelodeon history.
