Who was Kianna Underwood? Nickelodeon star who died in hit-and-run

Nickelodeon star Kianna Underwood has died after being struck in a hit-and-run accident. She was 33.

The Deputy Commissioner of Public Information confirmed to Page Six on Friday that officers responded to a call in Brooklyn’s Brownsville neighborhood, where Underwood was found with severe injuries and pronounced dead at the scene.

Authorities confirmed that the operator of the vehicle “did not remain on scene” and no arrests have been made as the investigation continues.

Underwood began acting at just 7 years old and landed her breakout role in 2005 when she joined the cast of Nickelodeon’s “All That” for its tenth season.

She also spent a year on the first national tour of “Hairspray” as Little Inez and voiced Fuchsia in the Nick Jr. show “Little Bill.”

Underwood was hired for the tenth and last season of “All That” to replace Jamie Lynn Spears — who left the show to start “Zoey 101.”

During her time on the Nickelodeon series, she acted alongside stars including, Kenan Thompson and Kel Mitchell.

Her last credited role was in “All That.” Once the show was canceled, she appeared to move back to her native New York City and stop acting.

Several “All That” alums have since spoken out about the alleged abuse which occurred on the show’s set. Underwood has never publicly done so.

Underwood lived a very private life out of the spotlight for the past 20 years, but appeared to be struggling in a resurfaced social media video from 2023.

In the clip, several people chatted with her and appeared to recognize her from her Nickelodeon days before she confirmed she starred in “All That.”

When asked to identify herself, Underwood said, “Kianna Underwood from ‘All That’ on Nickelodeon,” and continued to repeat it.

It’s unclear where she was living or if she was working.
