The 20-year-old actor, who played Oliver Oken on Miley Cyrus' hit Disney show, was preparing to head to trial over an arrest in Burbank, California for reportedly failing a breathalyser test in October (11).
He faced up to six months behind bars and a $1,000 (£625) fine after recently pleading not guilty to two counts of driving while drunk, but Musso has now reached a plea deal with prosecutors to put an end to the case.
On Friday (10Feb12), the star appeared in a California court and pleaded no contest to a lesser charge of having a blood alcohol level over the legal limit of 0.08. In return, he will be sentenced to 36 months of informal probation and be ordered to pay a fine and complete an alcohol awareness course.
In a statement released to TMZ.com, Musso says: "I appreciate the court allowing me to resolve my case in the manner it did today. In becoming an adult, I have learned first hand that stepping up and taking responsibility is the best way to move forward.
"I am especially thankful to my family and fans for their unwavering support and encouragement. I am glad to now put this in the past."
