Embattled R&B star CHRIS BROWN suffered more car trouble on Tuesday (21May13) when he accidentally hit another motor while driving through Beverly Hills with his on-again girlfriend Karrueche Tran.

After crashing his Porsche into a wall back in February (13), Brown was taking down insurance details again after he reportedly rear-ended a black Mercedes.

Brown and Tran were on their way to the studio when the accident happened on Tuesday afternoon.

X17.com reports no one was hurt and cops were not called to the scene.

Brown split from model Tran last year (12) to embark on a new romance with another ex, Rihanna, but that relationship has since fizzled out and the Kiss Kiss hitmaker appears to be back with his former flame.
