She was part of the cast of Pee-wee's Playhouse as Miss Yvonne "the Most Beautiful Woman in Puppet Land". Her character was especially flirty and known for providing steamy adult-like humor to the children's show. Miss Yvonne's character was a woman obsessed with beauty and cosmetics, who often flirts with Pee-wee and many of the other male characters on the show. Miss Yvonne is given the title "the most beautiful woman in Puppetland" by the puppet characters (especially Mr. Window who would usually introduce her). She wears a large brown bouffant-style wig that she doesn't like getting wet, gaudy dresses, and heels. She originated the role in the 1981 stage show The Pee-wee Herman Show, continuing it on the CBS television show Pee-wee's Playhouse, the 2010 Los Angeles stage revival, and the Broadway production which opened in November 2010 at the Stephen Sondheim Theatre.

She appeared in Raising Hope, Marvin Marvin, and Comedy Bang! Bang!. She guest-starred on Disney TV shows, including Austin & Ally and Good Luck Charlie in 2011. Also in 2011, at the Surflight Theatre, in New Jersey, she appeared in an all-female version of The Odd Couple, starring Cindy Williams and Jo Anne Worley.

Beginning in 2005 and until 2025, Stewart had a guest role as Charlie's mom, Bonnie Kelly, on the long-running, critically acclaimed series It's Always Sunny in Philadelphia, appearing in a total of 19 episodes. The season finale of Season 17, in which Stewart made her final appearance as Bonnie, aired posthumously and was dedicated to her.

Personal life Stewart never married or had any children. She and Paul Reubens were active participants with the Make-a-Wish Foundation and often appeared in character as Miss Yvonne and Pee-wee to bring happiness to terminally ill children. She and Reubens remained "the closest of friends" until Reubens' death in 2023, with Stewart attending to Reubens shortly before he died.

Death Stewart died in Los Angeles on February 21, 2025, at the age of 78 from cancer, which was found near her liver and gallbladder.
