Lynne Marie Stewart, a comedian and actress best known for appearing in Pee-wee’s Playhouse and It’s Always Sunny in Philadelphia, has died at 78, according to a report.
Stewart’s death was confirmed Friday to The Hollywood Reporter by a spokesperson for her former sketch troupe, the Groundlings. A cause of death was not disclosed.
An industry veteran, Stewart got her big break as Miss Yvonne (“the most beautiful woman in Puppet Land”) alongside Paul Reubens’ Pee-wee Herman, a role which she reprised throughout the 1980s. Stewart also portrayed Charlie Kenny’s mother on the long-running dark comedy series It’s Always Sunny.
She was a member of the Los Angeles-based troupe the Groundlings from the 1970s and 80s. “We are heartbroken to hear of the passing of our dear sweet Lynne Stewart,” the Groundlings wrote in a statement to THR.
“She wasn’t just the most beautiful woman in all of Puppetland—she was the most beautiful woman that we ever met, inside and out… She will be deeply missed.”
