Lynne Marie Stewart (1946–2025), Miss Yvonne on Pee-Wee’s Playhouse 

by Eric San Juan

Lynne Marie Stewart was a veteran actress known for playing Miss Yvonne on “Pee-Wee’s Playhouse” and Charlie’s mother on “It’s Always Sunny in Philadelphia.” 

Lynne Marie Stewart’s legacy 

Over a career spanning nearly 150 different roles, Stewart became best known for two strikingly different characters: the grandly charming Miss Yvonne, The Most Beautiful Woman in Puppetland, on “Pee-Wee’s Playhouse,” and Charlie’s strange, eccentric mom on “It’s Always Sunny in Philadelphia.” 

Stewart was part of the famed improvisational comedy group, The Groundlings, in Los Angeles when she met Paul Reubens (1952–2023). Their comedic sensibilities were a good match, so Stewart became Miss Yvonne for his onstage “Pee-Wee Herman Show,” a production that eventually morphed into the iconic 1980s TV series, movies, merchandise and more. Stewart’s portrayal of Miss Yvonne led her to becoming one of the most loved supporting cast members. 

She did much more on television than just befriend Pee-Wee. Stewart had early roles in “M*A*S*H,” “One Day at a Time,” “CHiPs,” and other series before enjoying a longer stint on “Laverne & Shirley.” Dozens of other parts followed, including appearances on “Dynasty,” “Night Court,” “Arrested Development,” “Grey’s Anatomy,” and “2 Broke Girls.” Stewart was introduced to a whole new generation of fans when she took on the role of Bonnie Kelly, Charlie’s mom, on “It’s Always Sunny in Philadelphia.” The provocative comedy showcased a different side of Stewart’s comedic talents, one far removed from her acting as Miss Yvonne.  

Stewart never left that lady behind, though. She and Reubens often appeared in character for the Make-A-Wish Foundation, helping lift the spirits of children with terminal illness. The pair remained friends their entire lives. 

Tributes to Lynne Marie Stewart 

I'm deeply saddened by the news of Lynne Marie Stewart's passing. A character actor with an impressive and exhaustive resume, I had the honor of doing a stage show with her a few years ago. As talented as she was kind, her beauty extended beyond Puppet Land and into the hearts of all she touched.

RIP Lynne Marie Stewart, who was so warm and generous playing my mom on several episodes of the Comedy Bang Bang TV show. I have a video of her dancing at the wrap party that I’ll try to dig up. Until then, here she is on our Christmas episode:youtu.be/yfszKSFyFMg

From Pee Wee’s Miss Yvonne to Charlie’s mom on It’s Always Sunny – and many, many more roles – Lynne Marie Stewart was a treasure. A huge loss.
