Efron appeared in great spirits as he hit up the Griffith Park Haunted Hayride with former “Hairspray” co-stars Julianne Hough and Brittany Snow … as well as director Adam Shankman.
our sources broke the story — the 25-year old actor completed 2 rounds of treatment earlier this year to combat the cocaine problem that took over his life.
Julianne”s brother Derek Hough snapped a pic with the group sharing hugs and smiles — and posted it online afterward saying, “Great time last night with great friends.”
