Remembering Christy Knowings
Christy Knowings, 'All That' and 'Sesame Street' Alum, Dies at 46 After Asthma Attack
Key Points
Knowings died on August 11, 2026, in the Los Angeles area after an asthma attack left her with brain damage and her family chose to remove her from life support.
Knowings appeared on Sesame Street from 2008 to 2011 alongside her real-life twin brother Chris Knowings, who later became a more frequent Sesame Street performer and also appeared in Spike Lee’s Crooklyn.
Knowings released a folk single titled 'To the World' in 2020.
On All That, Knowings’ favorite character was Gloria Bankhead, described by Knowings as an over-the-top Martha Stewart.
Knowings played multiple characters on All That, including Penny Lane and Jessica in the recurring 'Whateverrr!!!' sketches.
Christy Knowings, a cast member of Nickelodeon's beloved sketch comedy show All That, died on August 11, 2026, at age 46. She had suffered an asthma attack that left her with brain damage, and her family chose to remove her from life support, according to Deadline and The Wrap.
Her aunt, Tyleah Joseph, announced the death on Facebook. Knowings is the second former All That cast member to die in 2026. Kianna Underwood died in January after a fatal hit-and-run in Brooklyn.
A Timeline From Asthma Attack to Death
Knowings suffered an asthma attack on a Friday. The attack caused brain damage serious enough to require life support. Her family made the decision to remove her from life support on Tuesday. She died that same night, WMUR reported.
She was 46 years old and based in the Los Angeles area. Her aunt's Facebook post confirmed both the cause and the heartbreaking decision her family had to make. No further details about her health history were shared publicly.
Kenan Thompson Calls Her One of the Funniest People
Kenan Thompson, now a longtime star of Saturday Night Live, was among the first to pay tribute. He called Knowings "a real one" and said she was one of the funniest people he knew, according to Deadline.
Thompson and Knowings shared the All That stage from 1997 to 1999, during seasons four through six of the show. Knowings also returned as a guest during the show's 10th season. Other former cast members joined in offering tributes online after news of her death spread.
Her Favorite Character Was an Over-the-Top Martha Stewart
On All That, Knowings played several recurring characters. Her personal favorite was Gloria Bankhead — a character she described as an over-the-top version of Martha Stewart. She also played Penny Lane and Jessica in the popular "Whateverrr!!!" sketches, WISN reported.
Off camera, Knowings had a deep connection to her twin brother, Chris Knowings. The two appeared together on Sesame Street from 2008 to 2011. Chris went on to become a more frequent Sesame Street performer and also appeared in Spike Lee's film Crooklyn. Christy released a folk single called "To the World" in 2020.
Second All That Death in 2026 Stuns Former Cast
Knowings' death hit the All That community hard — especially because it follows so closely on the loss of another cast member. Kianna Underwood died in January 2026 after being struck by a vehicle in a hit-and-run incident in Brooklyn, according to KSBW.
Two deaths from the same cast in less than a year is a rare and painful loss for fans of the show. All That ran on Nickelodeon from 1994 to 2005 and launched the careers of several major comedy stars. Knowings was part of a generation that helped define the show's middle era.
