milli vanilli was a german musical group, formed in munich. they consisted of fab morvan (born 1966) and rob pilatus (1965-1998). they were popular in the late-1980s. in 1990, people found out that the group never sang anything at all. even at concerts, they pretended to sing (lip synching) while a recording was played. this created controversy and eventually led to the end of milli vanilli in 1990.
