"We don't not get along," the actor admitted. "We have very separate relationships with our kids at this point and it seems to work better that way because they are making their own decisions. As it turned out she and I did not share the same ethical views on parenting, including the continuing parenting of adult children."
Penn, 57, also admitted that he and his baby mama "don't have a lot of conversation," after divorcing in 2010 following 14 years of marriage.
The actor didn't speak more about how he and the House Of Cards star differ in terms of parenting, though he did say his relationship with kids Dylan, 26, and Hopper, 24, is "going great."
"They're amazing people," Penn said. "They're both acting and modeling, an industry that I'm not very interested in but they seem to have fun with it."
