Zac Efron quietly spent some time in rehab earlier this year, according to E! News.
Sources told the website the 25-year-old actor successfully completed treatment about five months back, insinuating he was there for alcohol issues. "He's healthy, happy and not drinking," one source told E! News. "He's taking time to focus on working."
Another source also confirmed to People magazine that the actor completed treatment, telling the magazine that Efron is "doing great," and "he's taking care of himself and it shows."
UPDATE: First reports indicated that Efron sought treatment for alcohol abuse, however, sources tell TMZ the actor went to rehab for a cocaine addiction.
Sources claim that the actor's problem "spiraled out of control" while filming the movie "Neighbors," in which Efron plays a frat boy. "It was common knowledge he was struggling with cocaine," one source told TMZ, while three other sources backed up the allegations, and also noted that he liked to "dabble" with the rave drug Molly.
Request for comment made by the Huffington Post to Efron's rep has not been returned at this time.
UPDATE 9/19: Zac Efron has reportedly had two rehab stints this year, not one, according to TMZ.
