Demi Moore and Ashton Kutcher fight over money while Mila Kunis waits

Actor Ashton Kutcher is reportedly planning to marry his actress girlfriend Mila Kunis -- just as soon as he gets his divorce from Demi Moore.

Kutcher and Moore split last year, but divorce proceedings have been drawn out by fights over money. Though Moore has plenty of her own, she's after the fruits of Kutcher's technology investments, which have risen sharply in the last year.

But Kutcher doesn't think he owes Moore any more money, saying the stocks didn't rise until after the pair split. But Moore says that because his venture capitol fund A-Grade investments was created while they were still together, she gets a chuck of the cash.

A source said Kutcher, 35, and Kunis, 30, "plan to get engaged soon." The two have known each other for 16 years, since they were costars on "That '70s Show."

"Being with Mila brought Ashton back to who he really is. He’s not playing the field, he’s focused on enjoying Mila and the happiness she brings. She doesn’t get jealous like Demi used to," the source said.
