Lynne Marie Stewart, who had supporting turns in “Pee-wee’s Playhouse” and “It’s Always Sunny in Philadelphia,” has died, her friend Cassandra Peterson confirmed via Instagram Friday. She was 78.

A lifelong Los Angeles native, Stewart began her career in comedy as part of the Hollywood-based sketch group “The Groundlings,” where she met Peterson and future “Pee-wee” co-star Paul Reubens.

Her early television career included roles as several different nurses on “M*A*S*H”, a guest spot on “Night Court” and a slew of recurring roles on “Laverne & Shirley.” In 1973, she had a brief role as a driver in “American Graffiti,” and in 1987 she appeared in the Arnold Schwarzenegger thriller “The Running Man.”

Stewart was best known for her role as Miss Yvonne, “the Most Beautiful Woman in Puppetland,” first originated in the 1981 Broadway stage version of “The Pee-wee Herman Show.” She would continue in the role across film and television, playing Miss Yvonne from 1986-1990 in five seasons of “Pee-wee’s Playhouse” as well as in feature films “Pee-wee’s Big Adventure” and “Big Top Pee-wee.”

6. I'll bet she and Cassandra were a force to be reckoned with! (LOL)

Cassandra Peterson (if you don't know) is "Elvira, Mistress of the Dark... and I can tell you personally she's a really cool lady. Funny, risque, and a livewire. I'm sure she and Yvonne kept everyone it stitches.

Crap... why does it seem like there's more death around than life, lately? I guess it's just me getting older and recognizing the ones dying more often.

7. In 1987, my new bride and I moved to Hollywood after a three month honeymoon of travel across the country

We met a California couple at a relatives wedding that summer that were moving out of their apartment in Hollywood and we needed a place when we arrived for the beginning of the semester as USC. When we moved in, we realized that the lady in the next apartment was Lynne Steward. She was so sweet. Occasionally, she would ask my wife to drive her to some audition across town. She always called me Doug even though that was not my name. She gave us a doll of her character on the Pee-Wee Herman Show. She signed it and again referenced me as Doug. She collected dolls and had large display cases of all kinds of dolls in her apartment. She introduced us one day to Cindy Williams. Paul Ruebens often visited her, and we ran into him frequently. I thought she would live forever.
