'All That' star Christy Knowings dies at 46 after reported asthma attack

Christy Knowings, best known for her work on Nickelodeon’s sketch-comedy series All That, has died at the age of 46, according to reports.

TMZ reported on Thursday, August 13, citing a family member, that Knowings suffered an asthma attack on Friday, August 7 and was subsequently hospitalised at a Los Angeles-area hospital.

According to the report, she was placed on life support before her family made the decision to remove her from life support on Tuesday, August 11.

Knowings joined All That in 1997 and appeared in more than 30 episodes of the Nickelodeon series before making her final appearance in 1999.

During her time on the show, Knowings played several characters, including Penny Lane and Jessica in the recurring “Whateverrr!!!” sketch alongside Amanda Bynes.

She joined the programme after appearing in And Now This, a Rosie O’Donnell sketch-comedy special for Nickelodeon.

Her former All That co-star Kenan Thompson paid tribute to Knowings on Instagram following news of her death.

Her later television work included three appearances on Sesame Street between 2009 and 2011, including episodes alongside her real-life twin brother, Chris Knowings.

She also released the folk single “To the World” in 2020.

All That ran for 10 seasons between 1994 and 2005 and featured performers including Thompson, Kel Mitchell, Amanda Bynes and Nick Cannon.  

Knowings is the second former All That cast member reported to have died in 2026, following Kianna Underwood’s death at 33 after a hit-and-run incident in New York.
