UPDATE: Conrad Hilton was released from jail on Monday, August 1.
More trouble for Paris Hilton's younger brother.
A Los Angeles federal judge revoked the 22-year-old hotel heir's probation and sentenced him to two months in prison on Monday after he failed a number of drug tests and was terminated from a substance abuse program
, U.S. Assistant attorney Alexander Schwab confirms to ET.
"The U.S. Attorneys Office was satisfied with the sentencing -- 2 months was the recommendation we made in court," Schwab tells ET.
"Conrad has 48 hours from noon this morning to report to jail. He has to report to the custody of the Bureau of Prisons," he added. "The U.S. Marshals Service will arrange exactly where he will report to for his time."
A source tells ET, "Conrad Hilton was in tears when the sentencing was announced. His parents were in the courtroom as well."
In 2014, Hilton was given three years probation and 750 hours community service after pleading guilty to attacking several flight attendants during a British Airways flight from London to Los Angeles. Then, in June of the following year, authorities confirmed to ET that Hilton was arrested again on suspicion of violating a restraining order obtained by his ex-girlfriend, Hunter Daily.
After he failed several drug tests, a judge ordered Hilton to check into a residential substance abuse treatment program in January.
During the sentencing hearing, Hilton reportedly asked the judge if he could serve his time under house arrest at his grandfather's Palm Springs, California home, stating that the family's Los Angeles residence was a "bad environment" for the troubled heir.
