Nickelodeon star Christy Knowings has died at the age of 46 after suffering an asthma attack which reportedly left her with brain damage.
The actor and comedian, best known for starring in the iconic children’s sketch show All That, died in Los Angeles on Tuesday after being taken to hospital days earlier.
According to TMZ, Knowings suffered an asthma attack on Friday and was subsequently placed on life support after sustaining brain damage. Her family ultimately made the decision to remove her from life support on Tuesday night, the publication reported. Her aunt, Tyleah Joseph, announced her death on Facebook the following day.
Knowings’ manager, Al Hill, remembered the performer as a woman of many talents who remained dedicated to her craft throughout her career. ‘Christy was a multi-talented lady,’ he told Variety in a statement. ‘Whether it was singing, acting, dancing, she was always creating. Always professional and dedicated to her work.’
Knowings became a familiar face to a generation of Nickelodeon viewers after joining All That in 1997. She was a main cast member for three seasons between 1997 and 2001, joining the programme alongside Leon Frierson and Danny Tamborelli for its fourth season.
Knowings had previously been discovered through the pilot of And Now This, a sketch comedy project produced by Rosie O’Donnell. Her arrival on All That put her alongside some of the biggest young comedy stars of the era, including Amanda Bynes, Kenan Thompson, Kel Mitchell, Lori Beth Denberg and Josh Server.
Nick Cannon and Gabriel Iglesias were among the other future stars who would later join the programme. Knowings eventually returned to All That as a guest star during its 10th season. Often described as a Saturday Night Live for children, All That first premiered on Nickelodeon in 1994 and became one of the network’s defining shows.
The sketch series launched or helped establish the careers of a remarkable number of stars, with its sprawling cast over the years also including Jamie Lynn Spears. Knowings also worked alongside her twin brother, Chris Knowings, during her career, with the siblings appearing together in three episodes of Sesame Street.
Her death marks the second tragedy to hit the All That family this year. Former cast member Kianna Underwood died aged 33 at the beginning of 2026 after being struck in a hit-and-run crash. Underwood appeared on the Nickelodeon series during its later years and also worked as a child actor on other television projects.
