Arnold Schwarzenegger Hires Divorce Lawyer Bob Kaufman

Arnold Schwarzenegger has officially lawyered up, according to TMZ.

Last week, Schwarzenegger's longtime attorney Martin Singer spoke out on Schwarzenegger's behalf, but now TMZ is reporting that the embattled former governor--who fathered a love child with longtime household staffer Mildred Patricia Baena--has hired celebrity divorce attorney Robert Kaufman to represent him in his split from estranged wife Maria Shriver.

Kaufman, who has represented Jennifer Aniston, Reese Witherspoon and Jessica Simpson in their splits, is known for keeping his celebrity clients out of the press.

According to TMZ, he has already talked to Shriver's attorney Laura Wasser about "moving forward" with divorce negotiations.

Shriver reportedly retained "disso-queen" Wasser before revelations of Schwarzenegger's love child surfaced two weeks ago. Wasser has represented dozens of celebrities in their divorces, including Robyn Gibson, Kate Walsh, Britney Spears, Angelina Jolie, and Kiefer Sutherland. Wasser, too, is known for maintaining a low profile for her clients.

A Schwarzenegger-Shriver split could be one of the most expensive celebrity divorces to date, with their combined net worth estimated at $500 million.
