Mila Kunis and Macaulay Culkin, who dated for nearly a decade before their split in 2011, are reportedly "not as friendly" as they could be post-breakup. 

In a 2018 interview on *Armchair Expert with Dax Shepard*, Kunis opened up about their relationship, admitting that the breakup was tough and she took full responsibility for the issues that led to their separation. 

She mentioned that she acted immaturely and hurt Culkin during their time together, which created tension between them.

While Kunis has since moved on and started a family with Ashton Kutcher, Culkin has kept a relatively low profile. 

Despite their long history together, Kunis revealed that they are no longer in close contact. She expressed regret for how things ended but acknowledged that the distance was necessary for both of them to move forward.  The two continue to focus on their own lives, without the lingering presence of their past relationship.
