Jason Derulo released his sophomore album ‘Future History’ last month and the 22-year-old tells MTV News that he “let it all hang out” on the follow-up to his self-titled 2010 debut. “‘Future History’ is the greatest accomplishment in my life,” Jason said. “I’ve been working on it for the past six months now. It is something that is very special to me. It’s an open book on my life. I wasn’t afraid to say anything: I just let it all hang out, and I told a story.” Watch his remarks below.
