London: 'Terminator' star Arnold Schwarzenegger's divorce from his wife Maria Shriver could cost him about USD 200 million.

The 63-year-old actor split from his wife of 25 years earlier this month and she is now set to begin divorce proceedings against him following the revelation he fathered a child with their former housekeeper Mildred ‘Patty’ Baena.

It is thought that their assets, estimated between USD 200 and 400 million, could be divided evenly, reported a daily.

While the estranged couple is believed to have a prenuptial agreement, because of the former California governor's infidelity and the length of the marriage, it could be voided.

They would then have to split their net worth as per Californian law. Although Maria hasn't announced official divorce plans yet, she is believed to have hired top divorce lawyer Laura Wasser.

"She'll get every last penny she is entitled to," a source said.

This divorce could be showbiz's biggest divorce settlement. It would dwarf the USD 1.4 million that basketball star Michael Jordan paid ex Juanita Vanoy in 2007, the current celebrity record. And it is more than twice what Tiger Woods is said to have given Elin Nordegren in their split.
