Justin Timberlake, CBS and Yahoo are teaming up to hold a contest to find an unsigned artist to perform with JT at the Grammys in February. Hopefuls can submit a sixty second video clip of them singing one of nine Grammy-winning songs selected by the SexyBack singer, which include Timerlake's own Cry Me a River as well as hits by Alicia Keys, Melissa Etheridge, Tina Turner, Aretha Franklin and Mariah Carey. The contestants will be cut down to twelve, and then the public can vote online to narrow the field to five, then three. The three finalists will attend the Grammys and will find out who won when Timberlake asks the winner to join him on stage. For more, go to Yahoo!, the Grammy site, CBS, or JT's homepage.
