Sean Kingston -- KIDDING! I Wasn't Drunk

Sean Kingston KIDDING! I WASN'T Drunk

Sean Kingston now says he WASN'T drunk when he got behind the wheel of his Lamborghini and roared down Sunset Blvd. Tuesday night, claiming he doesn't drink when he hits the clubs.

Kingston just went off on Twitter ... reacting to the TMZ video we posted this morning, which shows Kingston hopping into his Lambo, confessing he had "too much drinks" to answer our questions.

Kingston wrote, "For the record @TMZ I’m not 1 of these artist who u may think is living youngwild and free in Hollywood i care about my reputation and brand."

He added, "It was obviously a joke everyone that know me or been around knows that I don’t even drink in clubs..So can we stop with this."

Must be a brand new policy ... considering he was so drunk at Playhouse just a couple months ago he got out of the driver's seat because he didn't want to get a DUI.

So we gotta ask ...
