The actress and TV presenter, who was reported to be living apart from Carpenter last week, admitted that the couple are "working through" their issues.
She told DJ Howard Stern on his radio show: "We have come to a point where we are seeing [if] what will make everyone happiest is maybe to not live together, but continue to parent."
She continued: "We have different styles of living. I'm very messy. She's very not."
When asked about the cause of the split, O'Donnell said: "Kelli and I have a lot of issues and sex wasn't one of them."
The pair married in 2004 and have children Parker, Chelsea, Blake and Vivienne together, three of whom are adopted.
