Justin Bieber Dressed Up As 'Ninja' While Partying With Rita Ora [PICS]

Ninja??... Well he can normally be found proudly strutting into a club ready for a night out.

But Justin Bieber seemed to be feeling shy as he arrived at Los Angeles hotspot Warwick on Wednesday night to party with Rita Ora.

The Confident singer went undercover, zipping up his hoodie to hide almost all of his face as he jumped out of his car, and he kept up this bizarre charade as he was later seen leaving the club alongside the beautiful singer.... By the way who is this babe seen seating in the front seat of Bieber's ride as he was leaving the club... See below ...
