Lindsay Lohan to undergo random drug tests

Actress ordered to wear alcohol monitoring bracelet

A Beverly Hills judge on Monday ordered actress Lindsay Lohan to undergo random drug and alcohol testing and wear an alcohol monitoring bracelet after missing a probation hearing last week in a 2007 drunken driving case.

Judge Marsha Revel also said that Lohan, 23, had violated her probation, and the judge scheduled a new hearing in July to determine possible further sanctions.

Lohan, who agreed to the conditions on Monday, claimed she lost her passport in France last week, preventing an earlier return to Los Angeles for the May 20 hearing she missed.

Judge Revel said the "Mean Girls" actress has failed to complete alcohol education classes imposed as part of a 2007 sentence for reckless driving, drunken driving and driving under the influence of cocaine. Revel warned Lohan last October that she risked going to jail unless she took the matter seriously.
