Claim to Fame: Did that awesome "Shoulder Lean" song with T.I. back in 2006.

Accusation: Failed to pay $45,139.99 in taxes to the state of Georgia back in 2007 ... according to official docs filed with the GA Dept. of Revenue.

And It Gets Worse: Dro JUST had his bad ass Maserati repo'd 4 months ago after allegedly defaulting on the payments. Damn shame.

Did We Call Dro's Rep for Comment? You bet your ass we did ... no response.
