In year 2013. Justin went to a village in Guatemala. Trip was organized by Pencils of Promise, charity organization Bieber supported for years.
He didn't just traveled there to take a photo or two, he worked on one of the schools, carried building blocks and after that played with the kids that will go to that school.
Justin helped both with media attention that he brought but also personally working on the construction and he said that experience changed his life forever.
