Legendary actress Valerie Harper was hospitalized in Maine on Wednesday.
US Magazine reports the actress began feeling unwell before she was set to take the stage in a musical she is currently starring in.
The fire department confirmed with Entertainment Tonight that they received a call about an unconscious 75-year-old female who was taken to the hospital.
“She is resting comfortably and will remain in the hospital for observation for the time being,” the Ogunquit Playhouse said in a press release.
Harper was diagnosed with terminal brain cancer in 2013 and was given three to six months to live.
Since then, she has remained optimistic about her condition.
The actress is well known for her role as Rhoda Morgenstern on “The Mary Tyler More Show.”
