Justin's so excited and he just can't hide it! He's about to lose control and he thinks he likes it! Check out ALL these Whoa's Justin performed in his car at a red-light dance session.

Bieber balled out in the car yesterday while Hailey Baldwin was behind the wheel, blasting some tunes that got Justin going. We caught the whole thing in there side-view mirror of the couple's Lamborghini Urus and it's so CUTE!

The pair were headed to see J Lo's Hustlers at a local movie theater -- probably a good way to chill out before their stressful (but fun, we hope!) wedding weekend in South Carolina. Aren't these two gonna leave already and head to South Carolina? Don't they have any preparation to do before the big day on Monday? Or will they parachute in at the last minute, tie the knot, and jet off to a romantic honeymoon?
