Demi Moore finally files for divorce

New York: Demi Moore is finally filing divorce papers, 16 months after splitting up with Ashton Kutcher.

According to an insider, she's tired of trying to reach a confidential settlement with Kutcher, and that the couple's divorce could go to a trial, the New York Post reported.

"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," the source said adding that the actress has had enough.

Moore's lawyers could file paperwork in Los Angeles.

Kutcher filed divorce papers in December, a year after the couple split, but this would be the first time Moore responds.

She'd been hoping to quietly negotiate a settlement and then file the papers once an agreement was reached.

But negotiations got bogged down, and Kutcher has been very difficult during the talks, the insider said.

"After over a year of attempting to reach a settlement, Demi is definitely ready to move on," the source said of her decision to file.
