Last week, former Fly To The Sky member Brian Joo released his new digital single In My Head. With a music video just about to be released, it's now been revealed that he will be performing with Jason Derulo, the original artist of the song! Jason Derulo is an American R&B artist most famous for his 2009 hit Whatcha Say. Derulo originally created In My Head but Brian borrowed Derulo's track and covered the song with a little k-pop twist. Both songs were released around the same time and have been getting a lot of attention in their respective countries. Derulo was planning a tour and received requests to appear in Korea. His decision to go was assured when he watched the 2010 Vancouver Winter Olympics and saw Kim Yuna perform. The performance was so fantastic that he agreed to seek out the country that she was from. On the 17th and 18th, Derulo will be holding a special showcase at Club Heaven in Seoul. On the 19th, Derulo will go on air with Brian to put on a duet performance.
