Enrique Iglesias got busted trying to slip out of the driver's seat of his ride when cops pulled him over recently -- possibly because he knew he had a suspended license ... just a guess. According to Miami police, Iglesias was driving a white Cadillac Escalade back in May when cops pulled him over for driving in a closed off express lane. That's when his Houdini act began -- police say Enrique hopped into the back seat while his passenger slid into the driver's seat. The magic act bombed ... with cops, anyway. Enrique and the passenger, his tour manager, both got arrested ... and both have pled not guilty to obstruction. Enrique also pled not guilty to driving with a suspended license.
