Rapper Lil Wayne got low and busted by cops for drugs. Where's your Kool-aid smile now?

Law enforcement officials tell us Wayne, whose real name is Dwayne Carter Jr., was arrested near Yuma, Arizona last night on three felony counts: possession of dangerous drugs, possession of narcotics and possession of drug paraphernalia. Cops tell TMZ that the Drug Enforcement Agency was involved in the arrest - which means it's a big deal!

Wayne is currently in the custody of the Yuma County Sheriff's Department, where he'll be held pending his arraignment at 9:00 AM PT.

Wayne was arrested in Idaho last year for felony possession of drugs.

He should have dropped the drugs like a hot potato.
