Justin Bieber's winning streak came to a screeching halt when he went joyriding in a Ferrari Tuesday night ... and got stopped by cops, TMZ has learned.

Justin was cruising through West Hollywood around 6:30PM in a sick white Ferrari when an LA County Sheriff's deputy hit the strobes and sirens.

TMZ got a couple shots of the Biebs as he was pulled over. Witnesses say JB was cooperative while deputies took a closer look at his documentation ... and, of course, the sick ride.

Law enforcement sources tell TMZ Bieber did get ticketed, but it's unclear what law he allegedly broke.

Bieber's coming off a hell of a weekend -- hanging with Victoria's Secret supermodels, which led to the break up with Selena Gomez.

Rumor has it that Selena was the one that chose to call it quits! Even though Justin loves her he is ready to have fun, he’s only 18.
