Demi Moore is expected to file for divorce from Ashton Kutcher as early as Tuesday, according to a new report.

The NY Post first reported the story, with an insider saying that the decision -- which comes 16 months after their 2011 split -- was spurred by the couple's disagreement over what the financial settlement should be.

The actor, who pulled in $24 million for his work on Two and a Half Men in 2012, not only replaced Charlie Sheen on the show, but took his title of TV's highest-paid actor, and Demi "has had enough" of his lowballing, a source told the paper.

“Ashton made a lot of money after marrying Demi -- a lot more than she made -- but despite him becoming just as famous through her, he believes he doesn’t owe her that much."

Kutcher, who filed for divorce in Dec. 2012, could be headed to a trial with his ex, according to the paper. Both come to the table with legal powerhouses, as Kutcher is represented by attorney-to-the-stars Laura Wasser, while Moore has hired New York-based William Beslow.
