Selma Blair is mourning the loss of her mother Molly Cooke. The actor posted a touching tribute on Instagram one day after Cooke’s passing.

“My first person. My deepest heart still beats with what you gave me. I worship you, Mom,” Blair wrote on Instagram, posting a vintage portrait of her mother. Cooke died at home over the weekend.

Calling her mother “formidable, funny, quick, striking, generous” and “an original,” she noted that Cooke was a judge and “one of the only women in her law school class.”

💋My first person. 💋. My deepest heart still beats with what you gave me. I worship you , Mom. ❤️ Molly Cooke died yesterday. In her home. She was formidable, funny, quick , striking and generous. She often gave the shirt off her back, a trait I have adopted. Gifts of herself. My mother was a brilliant judge and one of the only women in her law school class. She was my first style icon, my muse , my prize. My whole life, I kept my eye on the prize. And , now, it is a very queer feeling to soften my gaze. She had many friends and admirers, cousins nieces, (and a nephew) a sister, a son in law. most of all, she had us, her girls, her grandchildren ,Jim, Nicholas, Frances and Arthur Saint. My sisters and myself, we loved her so much. Our lives will never be the same. Mom, Arthur understood you so sweetly and I am grateful and pleased you loved him. I wish I could pay a back at home tribute to you … to be in the company of my sisters: Lizzie, Katie, Mimi. Thank you for your love , your loyalty . Usually, it is when us girls are Together as sisters , when we can better show what an original you were , Mom. A great. I hold you from here. Oceans of love, Baby bear, the original Saint. #mollycooke 💛 #magistrate #mymoon #mymom #howardsternfan 🤷‍♀️😂⭐️ #enjoyedeverysecondofseinfeld #thankyou

Blair is the youngest of Cooke’s four daughters with her ex-husband, attorney Elliot Beitner whom she divorced when Blair was 23. Beitner died in 2012 at age 82.

Continuing her tribute to Cooke, Blair wrote, “She often gave the shirt off her back, a trait I have adopted. Gifts of herself.”

“A great. I hold you from here. Oceans of love. Baby bear, the original Saint,” she added.

Blair, 47, recently posted about Cooke on Mother’s Day, wishing she could spend time with her at her home in Michigan.

Blair, her son Arthur, and her boyfriend Ron Carlson have been quarantining in Los Angeles during the coronavirus pandemic because the actress is considered high risk for the virus due to her multiple sclerosis, which compromises her immune system.
