Demi Moore going after Ashton Kutcher`s fortune?

Los Angeles: Demi Moore is reportedly planning to hit her estranged husband, Ashton Kutcher, with a hefty financial settlement besides spousal support as the couple did not sign a prenup before getting married.

Kutcher allegedly cheated on Moore with other women on the occasion of their sixth wedding anniversary, reported Access Hollywood.

The 50-year-old actress formally filed her response to Kutcher`s divorce papers more than a year after the couple split and nearly three months after the actor filed for divorce.

"When they first got together Demi was worth a considerable amount more than Ashton, but obviously that`s changed drastically. Ashton is now worth at least USD 100 million whereas Demi`s not been bringing in the big bucks for years. Ashton has his `Two and a Half Men` contract, which pays him a cool USD 20 million a year and he`s also invested in several very successful internet startups including Skype and Foursquare.

"Ashton also has a very successful production company and a lucrative endorsement deal with Nikon. Demi doesn`t know the full extent of Ashton`s finances, but trust me, she will before a divorce settlement is finally reached," a source said.

Kutcher is currently dating his long time friend Mila Kunis.
