Jason Derulo's real name is Jason Joel Desrouleaux, but he changed the surname to make it easier to pronounce. He doesn't use the middle name bit because no one does really.
His debut album, 'Jason Derulo', was full of lamazing anthems such as 'Whatcha Say', 'Ridin' Solo' and 'In My Head'.
In 2011, he took the whole insufferable Euro dance ridiculousness 'thing' to its logical conclusion by sampling both Robin S's 'Show Me Love' and 'Day-O (The Banana Boat Song)' by Harry Belafonte on 'Don't Wanna Go Home'.
Derulo's second album, 'Future History', was released in September 2011.
