Four months after Catherine O'Hara's death, Macaulay Culkin is opening up about the loss of his "Home Alone" costar.
O'Hara, who played Culkin's mother in the 1990 Christmas comedy, died on Jan. 30 at age 71 following a "brief illness," which was later revealed to be a pulmonary embolism. Following news of her death, Culkin paid tribute to O'Hara in an emotional Instagram post, writing, "Mama. I thought we had time. I wanted more. ... I heard you. But I had so much more to say. I love you."
Culkin, 45, detailed his grief for O'Hara in an interview with Gentleman's Journal published Tuesday, May 12.
"When Catherine passed away in January, that hit me. That hit me pretty good, 'cause, you know, it was just too soon," Culkin told the magazine. "And I felt that we had unfinished business. I definitely feel like I had unfinished business with her, you know? I feel like I owed her a favor — and I don't like having an outstanding debt."
