“Zac was alone at home, and he leaned forward and fell into his coffee table,” an Efron source tells this week's STAR. “He broke his jaw on the table and was afraid to call an ambulance, so his friend took him to the ER.”
Despite the setback, the source said the bright-eyed High School Musical heartthrob continues to move in the right direction.
“He’s hired a sober coach to help him stay clean and keep his painkiller intake under control," the insider said, adding the actor "is tired of his addiction hindering his career!”
As we previously reported, news of the actor's personal troubles have sprouted up in recent months, as he's been tied to two rehab stints; drugs ranging from prescription pain killers to street contraband; and a party mate in Charlie Sheen.
