Nicky and Paris Hilton's little brother Conrad Hilton has been getting himself into some trouble lately!
The 21-year-old reportedly avoided jail time, but was sentenced to 90-days in a rehab facility after violating his probation. The hotel heir allegedly failed a drug test and was arrested on trespassing charges after he reportedly broke into the home of his ex-girlfriend.
This news comes after Conrad was charged with a felony for threatening the crew on a British Airways flight last year. His charge was eventually dropped to a misdemeanor assault charge and he was sentenced to three-years of probation, where he was ordered to avoid alcohol and drugs.
