If Maria Shriver terminates her marriage with Arnold Schwarzenegger, it could be one of the costliest celebrity splits ever, the New York Post reported Sunday.

Schwarzenegger and his jilted journalist-wife, who split after learning he had fathered a love child with his maid, might wind up slugging it out in a divorce that could decimate the action hero's fortune.

The power couple's worth has been assessed at between $200 million and $400 million. If Shriver decides to divorce her husband of more than two decades, she could walk away with way more than the $100 million slice of Tiger Wood's fortune that the golf great's ex-wife, Elin Nordegren, took home in their split last year.

The former first family of California is believed to have a prenuptial agreement. But after 25 years of marriage, and because of Schwarzenegger's philandering, that document could be tossed.

If the prenup does not stand up, the couple would likely split their net worth evenly, under California law.

Although she has not announced official divorce plans, Shriver has already hired one of Hollywood's top divorce lawyers, Laura Wasser.

A Schwarzenegger rep declined to comment.
