Justin Bieber put on an awesome show with his Ferrari, but he did it in front of a cop, and ended up getting busted for it.
The Biebs hit up The Grove in L.A. on Friday and when he left in his icy blue whip ... he punched it, peeling out of the parking lot. Seconds later an LAPD cruiser pulled him over, and apparently wrote him up. A source close to Justin tells us the singer made an illegal left turn.
We're sure his THREE top 10 songs will take the sting out of the ticket.
