Zac Efron celebrated his 26th birthday with a round of golf with his dad during the day and small shindig with friends — no girls allowed — at the Chateau Marmont, according to Us Weekly. The former "High School Musical" star, who completed a stint in rehab earlier this year for reported problems with cocaine and alcohol, was joined by Robert Pattinson, Joe Jonas and Michael B. Jordan for the festivities.
It's interesting that Jonas was there — he has reportedly been battling his own secret drug addiction, according to Star magazine. "He's been dealing with substance abuse issues for quite some time," a source says, adding that friends and family "have been begging him to seek help." Jonas has also recently been photographed with the same addiction specialist who helped Demi Lovato following her stint at a treatment facility.
