Justin Bieber, Rita Ora -- Que Ora Es? Time to Hook Up (VIDEO)

Justin Bieber and Rita Ora connected for sure Wednesday night ... and Thursday morning, too.

The Biebs and Rita arrived separately at Warwick nightclub in Hollywood, Justin shrouded in a hoodie. All pretenses flew out the window on the way out, when they left in Bieber's SUV at around 2 AM and beelined it for a late night/early AM meal.
