Nice to see you again, Zac Efron! The Parkland hunk, 25, resurfaced on his Instagram account on Friday, Sept. 27, nearly two weeks after it was revealed that he secretly entered rehab this past spring to deal with alcohol and cocaine problems. Flashing his famous smile and wearing backpacker-tourist gear against the stunning backdrop of Machu Picchu in Peru, the star look bright-eyed and healthy in the happy snapshot.
"Hey guys!" the High School Musical star writes. "Just returned from an incredible trip to Peru with my dad and wanted to thank you all for your support these past few weeks...means the world to me. Love you guys! - Z"
Once a regular on the L.A. club and party circuit, Efron had "been struggling with this problem for years and finally realized he needed outside help," a pal recently told Us Weekly.
Re-entering the Hollywood world of red carpets and after parties hasn't been easy, friends admit. "he's had to go from being a party boy to being completely sober," another friend says. "It's going to take time, but he's handling it well."
