People magazine is reporting that Blake Fielder-Civil is back in prison thanks to a recent positive drug test.

“I can confirm he has been recalled,” says Fielder-Civil’s lawyer Kate Anderson, declining to state the reason. (A source close to Fielder-Civil tells PEOPLE that he failed a drug test.)

The 26-year-old – who was sentenced to 27 months on charges of assault and attempting to pervert the course of justice – had been in rehab as part of his early release from jail.

Baron Hilton, Paris Hilton’s little brother, pled guilty on a charge of DUI this week in a Los Angeles courtroom. Barron Hilton was sentenced to three years’ probation, ordered to visit a morgue, pay $2,000 in fees and attend two alcohol education classes, a spokesman for the District Attorney’s Office said.

Paris Hilton’s young brother Barron Hilton was arrested for driving under the influence in Malibu, California today. The 18-year-old was pulled over by cops on Pacific Coast Highway in a black Mercedes-Benz at 8:30AM this morning.

E! Online’s Marc Malkin reported today that parents Kathy and Rick were considering withholding the 18-year-old’s $5,000 bail as an act of tough love.

“They don’t want to put up with this stuff anymore,” a source told Malkin.
