It's the hoity-toitiest drag race ever ... a Rolls-Royce with a big rapper at the wheel vs. a BMW.
It went down in Atlanta Friday on I-75, and it didn't take cops long to track down the high profile whips. They arrested rapper Rocko -- whose hits include "U.O.E.N.O." -- who of course was driving the Rolls. His friend was slumming it in the Beamer, which is Rocko's other car.
The friend tried to escape, but cops had real muscle cars and subdued the guy and arrested him as well for fleeing and eluding a peace officer.
Here's the rub. By the time cops spotted the cars they had slowed down, so they couldn't charge either with drag racing. Rocko got popped for driving on a suspended license.
And a side note -- that's a really pretty shade of blue in the mugshot.
