Cops to Tyrese -- Tag, You're It

Tyrese just learned a valuable lesson -- just because you pay an insane amount of money for a car, doesn't mean you can get away with not having a license plate on it.

Cops tell us Tyrese was pulled over while driving his Maserati through Hollywood Monday night for failing to have license plates on his car.

We're told the car is registered, but for some reason Tyrese either hasn't got the tag in the mail or just hasn't put it on the car yet.
