At the time of her death, she was starring in the award-winning Apple series “The Studio.”<\/p>\n O’Hara’s manager first confirmed<\/a> news of her death on Friday, Jan. 30.<\/p>\n The Los Angeles Fire Department told ABC News it received a call for medical aid earlier that day at 4:48 a.m. at an address connected to O’Hara. She was transported to a hospital in serious condition at that time, according to the LAFD.<\/p>\n O’Hara’s vast and prolific acting career<\/a> included more than 100 roles across TV and film. Most recently, she scored accolades for her role in the comedy series “Schitt’s Creek” as Moira Rose, a grandiose actress who is blissfully detached from reality.<\/p>\n Her portrayal of Moira in “Schitt’s Creek” — which also starred Eugene Levy, Dan Levy and Annie Murphy — earned her a Primetime Emmy Award in 2020, as well as a Golden Globe in 2021.<\/p>\n As news of O’Hara’s death spread last week, tributes<\/a> for the late actress poured in from across the world of entertainment.<\/p>\n![\"Academy](\"https:\/\/i.abcnewsfe.com\/a\/d8d6bdf4-7142-4b09-9887-03ebb7c4a3a3\/ohara-gty-er-260202_1770056251695_hpMain_4x5.jpg?w=375 "\\"Academy")
