Paris Hilton's brother, Conrad Hilton, was ordered on Wednesday to check into a residential substance abuse treatment program after a Los Angeles judge ruled he had violated the terms of his probation by failing drug tests.
The judge denied the prosecutors'request to put the 21-year-old hotel heir behind bars for 60 days and instead ordered him to spend 90 days in treatment. In addition to failing drug tests, authorities said Hilton also did not complete three prior treatment programs and traveled outside of California without getting authorization from his probation officer.
Last year, Hilton was given three years probation and 750 hours community service after pleading guilty to attacking a number of flight attendants in 2014 during a British Airways flight from London to Los Angeles.
In June, authorities confirmed to ET that Hilton was arrested again on suspicion of violating a restraining order obtained by his ex-girlfriend, Hunter Daily.
Paris Hilton's ex-boyfriend, Nick Carter, also had a run-in with the law this month after he was arrested for an alleged brawl at a bar in Key West, Florida. Backstreet Boys member AJ McLean defended Carter's behavior, telling ET that "everyone makes mistakes." Check it out:
