Kutcher allegedly cheated on Moore with another 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.
Kutcher is currently dating his long time friend Mila Kunis.
