The 20-year-old singer, who came in second place during the seventh season of American Idol in 2008, told audience members in Salt Lake City, Utah Monday that he plans to stop making music for two years in order to become a full-time Mormon missionary.
"It's not because someone told me that I was supposed to do it, not because I no longer want to do music anymore, but it's because it's the feeling that I felt that I need to do next in my life," he explained.
As the crowd erupted with applause, an overwhelmed Archuleta began to cry.
"It's the same feeling that I've always tried to follow in my life. It's the feeling that's allowed me to have the opportunities I've had, the challenges I've had to overcome, and the blessings, too," he added.
