Mila Kunis is getting candid about her Macaulay Culkin breakup.

Speaking on Dax Shepard's Armchair Expert podcast, the 34-year-old actress — who dated Culkin from 2002 to 2011 — took ownership for their split, saying it was "f--ked up" what she did and "f--ked up" how she did it.

"I had a horrible break up. I f--ked up. I was an a--hole in my 20s and I'll be the first to admit it," she explained. "When I got to be single I said, I just need to figure myself out. I genuinely need to know why I did what I did and, like, regroup myself as a human being."

Kunis went on to say it was "super hard" for her to forgive herself, though she declined to go into specifics about what happened between her and the Home Alone star.

"It's been so long, I feel like enough time's gone by," she continued. "I think enough mutual friends have been like everybody kind of forgave everybody for what went down."

In the near-decade since, Kunis and Culkin have both moved on. She married her former That '70s Show co-star, Ashton Kutcher, in 2015, and the couple now share two children. Culkin, meanwhile, is currently dating Disney alum Brenda Song.
