One version of the story is: Justin and Orlando were at the same celeb-packed restaurant in Ibiza. Justin walks by Orlando's table and tries to shake his hand. Orlando refuses (because... who wouldn't) to which Biebs responds with "She was good" OBVIOUSLY talking about Bloom's ex, Miranda Kerr. THIS is how the fight started. 

The first video shows Orlando throw the punch. The second video shows the aftermath where you can hear Bieber yell "What's up bitch!" LOL this can't get any better.. until..

Justin takes to instagram shortly after and posts a picture of Orlando Bloom's ex-wife, Miranda Kerr! I can't make this up. 

Orlando was seen hanging out with Selena Gomez in April while her and the Biebs were split up.

Obviously these guys have bad blood between them so I'm sure there's more to come. -@kitkatfisher
