Justin Bieber -- Hits On Hot Model Using Disney Pickup Line

Justin Bieber can put Bill Clinton to shame ... and if you doubt that check out this video of the Biebs zeroing in on a very hot model he ultimately reels in.

Bieber was cruising Rodeo Drive in a Rolls-Royce when he caught a glimpse of Jacqueline Younis ... who was in the middle of a photo shoot for Festoun clothing.

JB ordered his driver to stop ... and he then summoned the damsel to the Rolls ... and she obliged.

Bieber -- practically drooling -- took a pic with her and it looked like they were about to exchange numbers, but his fame got in the way ... too many photogs, too many fans.

BTW ... check out his pickup line, comparing her to a Disney character. It's super Goofy.
