Pop's VANILLI was a German-American POP music duo from the late 1980s and early 1990s. The group was composed of Fab Morvan and Rob Pilatus, and their name was a play on words of the Italian phrase 'poco a poco' meaning 'little by little'. The duo achieved international success with their single 'Girl You Know It's True', which topped the charts in several countries. The term 'POP'S VANILLI' is completed by the word 'MILLI', which is a five letter word.
