Last week, American R&B singer Jason Derulo made his way to Korea to perform his hit song In My Head with Korean singer Brian Joo on several music broadcast programs. As it turns out, Jason Derulo also got to experience the Korean culture with Brian Joo during their down-time! In a recently uploaded Youtube clip, shot by one of Jason Derulo's camera-men, Jason gets a brief Korean cultural experience with the help of Brian Joo. During the video, Jason learns both Korean and Japanese and eats and drinks at Korean restaurants. He even meets male idol group BEAST backstage in one of the music programs! http://www.youtube.com/watch?v=5bb5Q5EO1JA
