Zac Efron is serious about his sobriety.
The 26-year-old actor sought treatment for a reported cocaine addiction earlier this year, but he recently reached a milestone in temperance.
Earlier this month, Efron was spotted at a L.A. Lakers game wearing a blue Alcoholics Anonymous sobriety chip around his neck, which implies he has maintained his sobriety for six months.
The former "High School Musical" star has yet to go on record about his addiction issues, but he made sure to thank fans for their support in his first Instagram post after news of his rehab stays in became public knowledge back in September.
The actor, whose film "That Awkward Moment," hits theaters on Dec. 31, is currentlynursing a broken jaw after he slipped on a puddle of water in November.
