The "Bad Moms" star opened up about her ex during a candid interview on SiriusXM's "The Howard Stern Show," recalling that they got together "way, way after 'Home Alone,'" but Culkin's child star fame made dating difficult.
"He was huge. You couldn't walk down the street with him," she explained. "He always had this weird attraction, like fans just screamed when they saw him! They didn't know how to react. It wasn't like a normal response to a celebrity. Fans responded in a very abnormal way to him."
The "That '70s Show" actress was only 18 when she started dating Culkin and revealed that, despite being together for so long, she never had any intentions of tying the knot.
"Honestly, who knows?" she said when Stern asked if that was a sign she was never in love with Culkin. "But I know since before we started dating, since I was like, 16, I told my dad, 'Just so you know, I don't believe in marriage.' And my dad's like, 'What did I just create?' And then at one point I was like, 'I'll get married when gay people are allowed to marry.' I was like, 'This is not for me!'"
Her feelings have since changed, as Kunis is now married to Ashton Kutcher with a 1-year-old daughter, Wyatt, and another baby on the way. Kunis also opened up about how much worse paparazzi attention is now that she has a family.
"I know that after Wyatt was born, we had drones in our backyard," she revealed. "I wasn't home. They were at our old house. They didn't realize that we had moved." As for how she handles it, Kunis replied simply, "Not well."
