It's been a decade since Michael Douglas bid a bitter adieu to first wife Diandra, who reportedly walked away from their marriage with $45 million and houses in Spain and Beverly Hills. But she seems to have been doing some light reading in anticipation of the release of her ex-hubby's new movie, "Wall Street: Money Never Sleeps," and now feels she's entitled to another chunk of his moolah.

The New York Post says Diandra filed suit last month contending that she deserves half of the actor's earnings from the upcoming sequel to the 1987 greed-promoting, Gordon Gekko-centric Oliver Stone drama, citing a clause in their divorce agreement regarding "spin-offs" of his flicks.

"It's the same character, the same title, just years later," her attorney argued in Manhattan Supreme Court last week.

"The divorce agreement says that Diandra and Michael are to split 50-50 anything related to the films he made during their 23-year marriage," an insider explains to E! News. "She is seeking that money that she is owed. He, unfortunately, doesn't want to pay it."

But Douglas, who was hit with a variety of accusations from Diandra when their union flamed out in 1998 (he wed Catherine Zeta-Jones months after divorce was finalized in 2000, and they have two children, Dylan, 9, and Carys, 7), thinks enough is enough.

"He doesn't want her to be an albatross around his neck forever," says his attorney, who maintains that "Money Never Sleeps" is a sequel, not a spin-off. "They're not the same thing."

The exes, who appeared together in court back in April when son Cameron was sentenced to five years in prison for dealing drugs, are now awaiting a ruling on whether the case should be heard in New York or California.
