Britney Spears went berserk on Sam Lutfi this morning -- swearing at him in front of paps, yelling for him to "Please f**king get out of the way!"

Brit and Sam argued over who would drive Spears' new car, after pulling over near Britney's Summit Circle home -- and she screamed at Lutfi with the British accent, scolding him like a child.Guess Brit just tried to show him who's who's bitch.You go,girl,you're the mental case.
