Justin Bieber“s housemates — Lil Za & Lil Twist — are law-breaking, aggressive punks … who dangerously rocketed through the streets of Calabasas and cussed out their neighbor … and our sources has the footage.

The latest incident went down Thursday inside Bieber”s exclusive gated community — The Oaks — where one of Bieber”s neighbors witnessed Za and Twist tearing up the streets in JB”s cars … a black Range Rover and the infamous white Ferrari.

You”ll see a lady with a camera driving 25mph — the speed limit — as the two cars are stopped in front of her … one in the oncoming traffic lane.

As the woman passes Bieber”s cars … Za and Twist turn on the jets and screech past her at speeds way in excess of the limit.

It all comes to a head at one of the gates in the community, where Za gets out of his car, aggressively confronts the woman — and proclaims he”s a resident of The Oaks with this glib gem … “I live with Justin Bieber and you know I do.”

He then tells the woman, “F**k you. Get the f**k out of here.”

As for Bieber — he was in Miami to watch the NBA Championship.
