December 1 [10:00 EDT] -- One half of Milli Vanilli, the duo who were stripped of their Grammy and disgraced after it was learned they did not actually sing on their recordings, is now reportedly a wanted man in Los Angeles.

According to the Associated Press, a judge in Van Nuys Municipal Court has issued a warrant for the arrest of Rob Pilatus after the former Milli Vanilli performer failed to appear at a hearing for an alleged probation violation. The warrant is reportedly the second such document issued against Pilatus, with the first reportedly handed down on October 6.

The performer is reportedly on probation for four misdemeanor convictions handed down last year.

Along with his Milli Vanilli partner, Fab Morvan, Pilatus earned chart-topping success and a "Best New Artist" Grammy in 1990 with their breakthrough hit "Girl, You Know It's True." It was soon revealed that the duo did not sing on their albums, and lip-synched during performances, prompting the

National Academy of Recording Arts And Sciences to strip the duo of their Grammy Awards.
