Paris Hilton learned that justice is blind -- even to stars -- in 2007. The heiress has booked into custody after she violated the terms of a probation sentence she was serving following a drunk driving plea. In January, she was cited for driving on a suspended license. Hilton, who would sign a statement prohibiting her from the road, was pulled over in February and charged with violating her probation, which subsequently got her a 45-day jail sentence.
