Harvey interviewed Arnold for "OBJECTified" and raised the issue of divorce. Maria filed on July 1, 2011, several months after the story broke that Arnold had fathered a baby with the couple's housekeeper.
At the time she filed, two of their kids -- Patrick and Christopher -- were both minors. They're both adults now so custody is not an issue.
Sources say Maria would like the divorce to become final, but Arnold is not taking the necessary steps to end the marriage. But a source connected with Arnold tells TMZ, "Arnold is not standing in the way of the divorce. He's wants the divorce to become final in a way that is both sensitive to Maria and their kids."
"OBJECTified" with Arnold airs Sunday at 8 PM ET/5 PM PT, and again at 11 PM ET/8 PM PT, on FOX News Channel.
