They've been separated for over a year, but Demi Moore and Ashton Kutcher remain legally married.
And the reason why can be boiled down to one word, sources tell Radar Online: spite.
The actress is allegedly upset that Kutcher has moved on so quickly to Mila Kunis, as those former That 70s Show co-stars have been spotted kissing and cuddling in public for months now.
"Demi has instructed her attorneys to delay negotiations as much as possible," a source claims. "The main issue they have been fighting over has been the division of assets and the monetary settlement, but it's now gotten to the point where Ashton is willing to cave in to all of Demi's demands just to reach a settlement."
