"High School Musical" star Zac Efron kept his 26th birthday celebrations a low-key affair.
The actor, who completed a stint in rehab earlier this year for alleged cocaine and alcohol abuse, enjoyed a quiet dinner with his friends including Robert Pattinson, Joe Jonas, Michael B Jordan and his brother Dylan, reported Us magazine.
Earlier in the day, Efron played a round of golf in Carlsbad, California.
The actor recently credited his family for keeping him grounded and helping him to stay sober.
"My family's my rock. I know that they're not going anywhere. More and more I rely on my little brother to keep me grounded. He's 21 now," he had said.
