They have not been pictured together in public for four months 
 
 Hollywood couple Michael Douglas and Catherine Zeta Jones’ 13-year marriage is over, it was claimed this week. 
 
 An insider said: “Michael is going to announce the split soon. Catherine is fighting to save the marriage but he’s had it.” 
 
 But another report said she was set to start a multi-million divorce battle. 
 
 Earlier this week Michael, 68, was pictured arriving in Sardinia by private jet but mum-of-two ­Catherine, 43, was nowhere to be seen. 
 
 They have not been pictured together in public for four months. 
 
 Reports of a marriage crisis were denied earlier this year but Michael’s spokesman would only say yesterday: “I won’t talk about that.”

He helped her when she had a stint in rehab for bi-polar disorder. ||||| The divorce battle is on between former lovebirds, Michael Douglas and Catherine Zeta Jones and it’s not about property or cold hard cash. Instead while slowly but surely separating after 13 years of marriage these two are at bitter odds over their two children. CDL has already reported that the couple first split last year to test the waters of living apart and it seems to be the way that they are happiest.

 According to the Sept. 2nd print edition of Star Magazine Michael is sick of letting Catherine call all of the shots, especially since he considers her to be pretty unstable. Her bipolar disorder has caused manic episodes that Michael can no longer suffer through and it’s a huge reason for the couples’ split. Catherine has always controlled what happens with the kids but in recent months Michael has stepped up and proven that he now intends to be a very hands on father. 
 
 Last week Michael and the kids, 13 year-old son Dylan Michael Douglas and 10-year-old daughter Carys Zeta Douglas, boarded a flight for Germany completely against Catherine’s wishes but in the end there was absolutely nothing that she could do to prevent him from leaving the country with the kids. Catherine is accustomed to getting her way and she figured that custody of the children would be a no-brainer. Instead Michael is absolutely prepared to fight her tooth and nail for the kids. 
 
 It’s funny, I always thought that these two had one of the more stable marriages in Hollywood, didn’t you? Are you surprised that they are on the fast track towards a messy divorce? Who do you think should have primary custody of the kids? Should it be a joint situation or do you think one parent is clearly more fit than the other? Tell us your thoughts in the comments below! 
 
 Editor’s Note: A few months ago a rep for the separated couple denied the divorce reports but this weekend when speaking to The Mirror about the couple’s problems and impending legal separation they would only say: “I won’t talk about that.” After Michael humiliated his already unstable wife by saying that his throat cancer was caused by Catherine’s STD you knew that it was all over but the crying for their marriage.

– Michael Douglas and Catherine Zeta-Jones have weathered a lot together (his cancer; her bipolar disorder; his son's struggles), but their 13-year marriage may be kaput. The Mirror cites multiple reports claiming a divorce is imminent. One such report in the Daily Star claims Douglas is the one who wants the divorce while Zeta-Jones is fighting to salvage their union; another reportedly claims it's the other way around. Says a Douglas spokesman, "I won't talk about that." The meatiest report is in Celeb Dirty Laundry, which cites the upcoming print edition of Star magazine. Supposedly, Douglas thinks Zeta-Jones is unstable and shouldn't be "calling all of the shots" in their marriage, and last week he reportedly took their two kids to Germany against her wishes. The two have not been photographed together for four months, and they've already denied rumors of marital problems earlier this year.
