AceShowbiz - Sean Penn's son has been fined $1,000 (£755) after pleading no contest to a drug charge.
Hopper Penn, whose mother is actress Robin Wright, was arrested alongside his girlfriend, Uma Von Wittkamp, during a traffic stop in Nebraska on April 4.
Nebraska State Patrol officers suspected they were in possession of drugs and conducted a search of the vehicle, which reportedly turned up marijuana, amphetamine pills, and mushrooms.
They were taken into custody and initially charged with felony drug possession, but their counts were subsequently reduced to misdemeanours for attempt of a felony.
The young actor, 24, and Uma, 26, both pleaded no contest, and were each ordered to pay $1,000, according to The Associated Press.
Penn's famous parents, who were married from 1996 to 2010, have remained silent about their son's arrest, but last year, Hopper revealed his father's tough love forced him to confront his drug demons in rehab.
After one binge landed him in hospital, Sean told his wayward son he had to seek professional help, or be kicked out onto the street.
"I was doing a lot of stuff but meth(amphetamine) was the main one that brought me down," he told Britain's ES magazine. "I went to rehab because I woke up in hospital and my dad said, 'Rehab? Or bus bench?' I was like, 'I'll take the bed'.
"Thank God I got out of that because that was the worst time in my life. Because it's not fun when it gets to a point where you just need it."
Hopper also credited his dad's decision to cast him in a minor role in his 2016 drama "The Last Face" with helping to keep him on the straight and narrow.
"I know he kind of wrote the part for me," he added. "He really wanted to work with me and it ended up being great. But yeah, maybe it was about giving me just a little structure."
