It's Jason Derulo's real surname!
I have no idea what he actually does, except for the fact that he sang in 'Mmm Watcha Say'.
Simply, I found his surname interesting. Fancy, rite? The Dominion of Desrouleaux's motto is: 'Jason Derulo knew we couldn't read'. And it's true. I bet u that a majority of people might
pronounce 'Desrouleaux' as 'Dez-roo-leoh', which is why he took on the stage name 'Derulo'.
