Conrad Hilton — little brother of Paris and Nicky and worst airplane passenger ever — was sentenced to two months in jail after admitting to using drugs while on probation.

The 22-year-old heir to the Hilton hotel fortune is serving three years' probation (and 750 hours of community service) as a result of his very public and volatile meltdown on a flight from London to L.A. in 2015.

A U.S. Attorney's Office spokesperson told People that "Hilton admitted in court to using marijuana, synthetic cannabinoids and cocaine." Hilton previously failed a mandatory drug test and was sent to rehab in January, but a court denied a request for jail time. According to authorities cited by Page Six, he also "violated probation by trespassing, failing drug tests, failing to complete three treatment programs and traveling out of California without permission from his probation officer."

The future inmate has until Wednesday to turn himself in and begin his two-month sentence... you know, this time.
