Chris Klein has owned up to his mistakes.
The actor has served 96 hours behind bars on his own accord for his second drunk-driving arrest and has also completed two months in a live-in rehab facility.
Klein, 31, personally appeared Friday in a Van Nuys, Calif., court where he pleaded no contest to DUI and was sentenced to four years’ probation, fines and an 18-month alcohol education class.
“I apologize for my wrongdoing and I really appreciate that the court gave me the opportunity to prove how seriously I took all of this,” Klein told Judge David B. Gelfound.
