She is now at her home in Venice, California, but cannot leave until June 29.
"She is now confined to the interior premises of her home at all times," said Steve Whitmore, the Los Angeles Sheriff's spokesman.
The actress was last month ordered to to undertake three years probation, serve 120 days in jail and complete 480 hours of community service for jewelry theft and breaching the terms of her 2007 probation.
