Arnie could pay £155m for the biggest showbiz divorce in history

Arnold Schwarzenegger's divorce from Maria Shriver could cost him £155m, making it the biggest settlement in showbiz history.

The Terminator star 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 housekeeper Mildred 'Patty' Baena, and it is thought their assets - estimated at £310m - could be divided evenly.

While it is believed that the couple signed a pre-nuptial agreement, Shriver may challenge it in the light of her husband's infidelity and length of their marriage. Instead, they would then have to split their net worth, in line with Californian law.

Shriver could therefore pocket a record divorce payout - even surpassing the £100m basketball star Michael Jordan paid ex Juanita Vanoy in 2007.

A niece of former US president John F. Kennedy, Shriver is said to have hired celebrity divorce lawyer Laura Wasser to represent her.

Meanwhile, Schwarzenegger's latest movie Cry Macho, which was due to be released next year, has currently been put on hold.
