The arrest comes just five days before the hip-hop star is set to stand trial on two assault causes in Manhattan Criminal Court.
Police stopped the rapper, real name Trevor Smith, at 12:48 a.m. after they noticed the windows of his GMC Yukon Denali were excessively tinted.
Officers claim they smelled "a strong odor of alcohol" on Smith's breath and "he dropped his wallet to the ground" when he attempted to show them his identification.
An on-site sobriety test found his blood-alcohol level was .147--above the legal New York State limit of .08.
Smith will be arraigned later today.
This is the latest of a string of legal troubles for the rapper. In February, he was arrested for allegedly driving on a suspended license and aggravated driving.
Next week, his trial for the alleged December assault of his driver and an August assault of a fan, is set to begin.
