Demi Moore is seeking spousal support from Ashton Kutcher.

The actress has filed divorce papers in California against the 'Two and a Half Men' star - 16 months after their 2011 split - and though she is said to know a judge would never agree to her demands as she out-earns her estranged spouse, insiders say she is making the move to show Ashton was a ''bad husband'' who she was ''really hurt'' by.

However, other sources also told gossip website TMZ the former couple are in the midst of negotiating a final settlement and Demi - who is worth an estimated $150 million compared with the actor's $135 million - is aware that the more she asks for, the better she is likely to do in the end.

Ashton - who is now dating 'Oz the Great and Powerful' actress Mila Kunis - filed for divorce in December 2012, but the estranged spouses have been engaged in a battle over money ever since.

However, it was recently claimed Demi has reportedly decided to put an end to the feud in order to move on for her life, even though she feels she deserves a better settlement from TV's highest-paid actor Ashton, who earned a staggering $24 million in 2012 for his sitcom 'Two and a Half Men'.

The source added: ''Ashton made a lot of money after marrying Demi - a lot more than she made - but despite him becoming just as famous through her, he believes he doesn't owe her that much.''

The pair are said to be close to reaching a deal.
