Zac Efron has finally broken his silence post-rehab by sharing his pic on Instagram against the stunning backdrop of Machu Picchu in Peru.
The image shows the 25-year-old actor looking bright-eyed and healthy.
In the photograph, Efron can be seen smiling while wearing backpacker-tourist gear, Us Magazine reported.
The 'High School Musical' star wrote as a caption that he had just returned from an incredible trip to Peru with his dad and wanted to thank his fans for all the support that they gave him.
Efron had been admitted in rehab this past spring to deal with his alcohol and cocaine problems.
