After months of trying to negotiate a confidential and amicable settlement with Ashton Kutcher
, Demi Moore
is expected to file a divorce response, putting their case on course for a possible trial, reports the New York Post
's Page Six.
The couple, who married in September 2005
in a Kabbalah ceremony at their Beverly Hills home, split in 2011
Kutcher, 35, filed for divorce
in December 2012, but negotiations on a settlement stalled, reportedly over finances, according to the Post
– quoting a source who said Kutcher (who last year reportedly earned $24 million year from the CBS hit Two and a Half Men
) was "very difficult during the talks. You could even say he has been hostile."
Since their break-up, Kutcher has been dating his That '70s Show
costar Mila Kunis
– prompting stories that Moore was jealous
. Kutcher took Kunis home to Iowa over Christmas
to spend time with his family.
In January, Moore, 50, was seen on several dates
with Pink Taco restaurant chain owner Harry Morton, 31, a source told PEOPLE.
Reps for Moore and Kutcher have not commented.
