Demi Moore wants Ashton Kutcher to pay for her home renovations.

This comes after it was revealed the couple - who announced their split in November 2011 - are locked in a battle over $10 million, with Demi asking for the eight-figure sum due to Ashton's involvement in a venture capital fund worth $100 million.

The 'Two and a Half Men' star announced his new technology start-up investment firm A-Grade, which is a partnership with Madonna's manager Guy Oseary and billionaire Ron Burkle, earlier this month with an estimated value of $100 million and Demi believes she is entitled to a piece of the actor's newfound fortune.

However, Ashton - who owns 20 per cent of the company - insists his profits from the company aren't communal as he made his millions after their split.

A source previously said: "Ashton and Demi are still not divorced and no settlement has been agreed, even though they have been in negotiations for over a year. Ashton made a lot of money after they married, but he doesn't believe he owes her as much as she is asking for."

Ashton - whose stake in the firm is worth $20 million - reportedly told the 'Ghost' actress' lawyers the investment firm hadn't made any money and he only put one million dollars into it, but the company has been moving forward in trying to attract outside investors by boasting its nine-figure value.
