Not another celebrity in rehab . I was shocked when i got this news .

The high school musical favorite actor and celebrity ,  25-year old Zac Efron  who just came out of rehab for an  addiction  earlier this year for cocaine addiction .Zac, whose new movie Parkland recently premiered at the Toronto International Film Festival, allegedly completed a brief stint in rehab about five months ago, according to a new report from E! Online. 

it was said that the problem spiraled out of control during the filming of Seth Rogen’s movie “Neighbors,” which was shot during a narrow time frame beginning in April. in which he plays the head of a fraternity house. The flick was shot in a short period of time beginning in April, and Zac, 25, reportedly missed several days of filming due to his alleged addiction, a source close to the film tells TMZ.

Sources say that Zac — who also starred in the movie — was a no-show on a number of days. As one source connected with the film tells us, “It was common knowledge he was struggling with cocaine.” Three other sources confirm … Zac’s problem was rooted in cocaine, but say he also dabbled in Molly — a pure form of Ecstasy, and a popular drug in clubs and raves.

We’re told … early this year, Zac and some friends went on a coke rager in a room at the SkyLofts at the MGM Grand in Vegas … and caused around $50k in damage. No word on who took care of the bill.

How awful! We hope these reports aren’t true, but if they are, Zac did the right thing by seeking professional help and kicking his addiction before it was too late.

What do YOU think, HollywoodLifers? Are you surprised by the report that Zac went to rehab for a cocaine problem? Let us know.
