Christy Knowings, the former “All That” star, has died at 46 after an asthma attack left her on life support.
Knowings passed away Tuesday, according to reports. She was 46.
The Nickelodeon alum was placed on life support at a Los Angeles hospital last Friday.
Her family ultimately made the decision to take her off it, sources said.
Knowings was a regular on the sketch comedy series “All That” for three seasons from 1997 to 2000.
She starred alongside Amanda Bynes, Nick Cannon, and Kenan Thompson during her run.
She played various characters, including Jessica and Penny Lane.
Her last television appearance came as herself on “Sesame Street” alongside her twin brother, Chris.
The siblings appeared in three episodes of the children’s program from 2008 to 2011.
Additionally, she released the 2020 track “To the World.”
Before her death, the former child star maintained a low profile on social media.

Her twin brother Chris also found success in children’s television, landing a long-running role on “Sesame Street.”
The siblings’ joint appearance on the PBS series marked a rare on-screen reunion.
Knowings’ music release in 2020 suggested she had continued pursuing creative projects in recent years.
Her Black Beat magazine cover indicated she remained a recognized figure in entertainment circles.
The magazine feature was scheduled for release in mid-2026.
