The world of comedy is mourning the loss of Lynne Marie Stewart, who charmed audiences for years with her unforgettable performances. Best remembered as the glamorous Miss Yvonne on Pee-wee’s Playhouse and as Bonnie Kelly, Charlie’s quirky mother on It’s Always Sunny in Philadelphia, Stewart died unexpectedly at age 78 due to complications from a tumor. The tumor, located near her liver and gallbladder, was discovered late in December 2024, bringing a sudden halt to her vibrant career.
Stewart's career trajectory shifted dramatically in 1981 when she debuted as Miss Yvonne in The Pee-wee Herman Show stage production. Her portrayal of the flirtatious 'Most Beautiful Woman in Puppetland' became a signature role, which launched her into broader fame with the beloved children's program Pee-wee’s Playhouse from 1986 to 1991. Her onscreen chemistry with Paul Reubens, who brought Pee-wee Herman to life, was magical—a partnership praised for its comedic brilliance throughout various films and specials featuring the duo.
Besides her work associated with Pee-wee, Stewart's acting resume boasts an array of beloved characters. This talented actress made notable appearances in movies like American Graffiti and Bridesmaids, as well as TV shows such as M*A*S*H* and Arrested Development. Her contributions to comedy were heavily influenced by her collaboration with The Groundlings, a comedy troupe renowned for shaping the careers of many entertainment superstars.
Tributes poured in from co-stars, friends, and fans who were touched by both her exceptional talent and her spirit. Charlie Day, known for his role in It’s Always Sunny in Philadelphia, shared his admiration, calling her a “brilliant and talented” performer, while the legendary Danny DeVito fondly remembered her as having a “wonderful spirit.” Adding to the warmth of remembrance, Cassandra Peterson, famously known as Elvira, praised Stewart as one of the “kindest, sweetest, funniest women” she had ever met.
