Justin walked passed Orlando's table and attempted to shake his hand. Orlando refused, because, get the fuck away from me, and then "Bieber said something rude to Orlando, like 'She was good,'" alluding to hooking up with Orlando's ex-wife Miranda Kerr.
Bieber was spotted hanging with Bloom's ex at 2012 Victoria's Secret fashion show, while Orlando got tight with Selena Gomez back in April.
Justin posted a pic of Miranda Kerr on his Instagram today but deleted it after a few minutes.
