Macaulay Culkin is remembering his 'Home Alone' mom, Catherine O'Hara. Sharing an image from his 2023 Hollywood Walk of Fame ceremony, he wrote: "Mama. I thought we had time. I wanted more. I wanted to sit in a chair next to you. I heard you. But I had so much more to say. I love you. I’ll see you later." Catherine died Friday at her home in Los Angeles following a brief illness. She was 71. | Entertainment Tonight
