Mila Kunis and Macaulay Culkin Split

Actors Macaulay Culkin and Mila Kunis have broken up after an eight-year relationship. INSIDE EDITION has the details.

Mila Kunis and longtime boyfriend Macaulay Culkin have officially ended their eight-year relationship.

Kunis, 27, who is earning raves for her performance in Black Swan, and Culkin, 30, split amicably and remain friends, according to her rep.

In a 2009 interview, Kunis said of Culkin, the former child star of the Home Alone movies: "We grew up together. You find a steady rock in your life and that's all you need. We have our ups and downs, but work through them."

Kunis and Culkin actually broke up awhile ago, but say they kept quiet so the news would not affect the publicity tour for Black Swan.
