Most Shocking Concert Moments: Milli Vanilli Lip Sync on Stage

DATE: July, 21 1989

WHAT WENT DOWN: Today it's cool for Britney Spears to flub her lip-sync shows in Vegas, but when Milli Vanilli got caught faking the funk, it spelled the beginning of their end. The dreadlocked duo was performing their biggest hit, 'Girl You Know It's True,' at a show in Bristol, CT when the vocal track started to skip. Though the crowd didn't seem to mind, the group was crucified by critics who began questioning their talent. A year later, the pressure of public scrutiny led the group's manager revealed that Rob and Fab didn't actually sing on their award-winning records. Fans called for blood after the announcement and the band was eventually forced to return their 1990 Best New Artist Grammy.
