Jason Wahler was sentenced to two months in jail for punching a city worker and tow truck driver during an altercation last year.
Wahler, 20, star of MTV's "The Hills" and "Laguna Beach: The Real Orange County," was also ordered to attend a one-day program at the Museum of Tolerance for uttering racial slurs during the September incident, authorities said.
Wahler is white. Two of the victims are black, authorities said.
According to prosecutors, Wahler was traveling in a car with friends when their vehicle was blocked by a tow truck attempting to move an illegally parked car.
Wahler jumped out of his vehicle and began yelling at the city worker and one of two tow truck drivers. Wahler, whose blood alcohol level was .22 percent at the time, then punched one tow operator, as well as the city worker, authorities said.
One of Wahler's companions also kicked the tow operator and spit in his face, the City Attorney's office said Tuesday.
Wahler pleaded no contest to one count of battery. He was sentenced to 60 days in jail, and was ordered to attend anger management classes and Alcoholics Anonymous meetings.
Wahler was arrested late Friday in Greenville, N.C., for underage drinking and resisting a public officer during a raid against a local nightclub. He was released on $1,000 bond several hours later.
The Associated Press was attempting to reach a representative for Wahler on Wednesday.
