Milli Vanilli was a pop music duo from Germany, consisting of Rob Pilatus and Fab Morvan. They gained fame in the late 1980s and early 1990s with their catchy songs and energetic performances. Their debut album, "Girl You Know It's True," became a commercial success, earning them a Grammy Award for Best New Artist. However, the duo faced controversy when it was revealed that they did not sing on their records. Instead, the actual vocals were performed by other artists. This scandal led to the revocation of their Grammy Award and significantly impacted their careers and public image.
